[SILOptimizer]Refactor ObjC dependencies in sil_combine tests
[gardening] Improve consistency in start of file header comment
This is another bug exposed by changing the instruction allocation. Depending on the allocated address of new SILBuilder instructions, those instructions were added to the SILCombiner worklist or not. This bug didn't cause any crashes or miscombiles, but resulted in a non-deterministic result of SILCombine.
…mized. Now we have 3 cases. 1. OptimizeNone (for functions with too many basicblocks and too many locations). Simply return. 2. Pessimisitc single iteration data flow (for functions with many basic blocks and many locations). 3. Optimistic multiple iteration data flow (for functions with some basic blocks and some locations and require iterative data flow). With this change stdlib and stdlibunittest has some changes in dead store(DS) eliminated. stdlib: 202 -> 203 DS. stdlibunittest: 42 - 39 DS. Compilation time improvement: with this change on a RELEASE+ASSERT compiler for stdlibunittest.

Existing tests ensure correctness.
The functions in `cmpcodesize.compare` do several things: they call otool, they use regex matchers to extract information from otool's output, and they output that information using `print()`. Currently, the only way to test cmpcodesize is via functional tests: ones that actually run on a dylib like libswiftCore.dylib. This takes a lot of time and is difficult to fully automate. By extracting otool calls from `cmpcodesize.compare`, we can test those in isolation. Furthermore, future commits can test the functions in `cmpcodesize.compare` using canned strings, instead of actual otool output.
`cmpcodesize.compare` has a few responsibilities: matching regular expressions on otool output, and storing the results of those matches in dictionaries. Begin extracting the regular expression matching into a separate file, `cmpcodesize/regex.py`. This makes the code more modular, and allows for finer-grained unit tests.
Fixes a bug, introduced in a1f6040, in which `cmpcodesize -l /path/to/file` would only output the *first* label, instead of listing all of them.

Having a separate address and container value returned from alloc_stack is not really needed in SIL. Even if they differ we have both addresses available during IRGen, because a dealloc_stack is always dominated by the corresponding alloc_stack in the same function. Although this commit quite large, most changes are trivial. The largest non-trivial change is in IRGenSIL. This commit is a NFC regarding the generated code. Even the generated SIL is the same (except removed #0, #1 and @local_storage).

… the left-hand side. Rather than using a specialized matching rule in the type checker that depends on having default arguments in types, use call argument matching consistently. Note #1: This (correctly) breaks some existing code that depends on inferring a parameter type of () for a single-argument parameter from a no-argument function type(). Note #2: This pessimizes a code completion test, where the code completion engine seems to depend on some quirks of argument matching. The "type relationship" matching needs non-trivial work.

…mer::handleDiagnostic
Add test case for crash triggered in `swift::PrintingDiagnosticConsumer::handleDiagnostic`.
Current number of unresolved compiler crashers: 135 (5186 resolved)
Assertion failure in `llvm/lib/Support/SourceMgr.cpp (line 290)`:
```
Assertion `(size_t)llvm::sys::locale::columnWidth(I->getText()) == I->getText().size()' failed.
When executing: void buildFixItLine(std::string &, std::string &, ArrayRef<llvm::SMFixIt>, ArrayRef<char>)
```
Assertion context:
```
// FIXME: This assertion is intended to catch unintended use of multibyte
// characters in fixits. If we decide to do this, we'll have to track
// separate byte widths for the source and fixit lines.
assert((size_t)llvm::sys::locale::columnWidth(I->getText()) ==
I->getText().size());
// This relies on one byte per column in our fixit hints.
unsigned LastColumnModified = HintCol + I->getText().size();
if (LastColumnModified > FixItLine.size())
FixItLine.resize(LastColumnModified, ' ');

The code here is unprincipled, and mixes archetypes from multiple sources: 1) The callee's generic environment 2) The caller's generic environment 3) Any random archetypes appearing in the original types of typealiases, which could come from any generic environment Initially, an UncurriedCandidate's type starts out as #1, and then we sometimes set it to type #2 if the candidate is a method on a base class. We get swiftlang#3 by virtue of walking the original types of SubstitutedTypes created as part of dependent member type substitution. However, it turns out the real reason the SubstitutedType walk existed was so that #2 archetypes that appear in the UncurriedCandidate's type map to themselves. This doesn't require looking at the original type of a SubstitutedType at all; instead we just walk the UncurriedCandidate's type normally, collecting archetypes. If we do this, the code doesn't (erroneously) pick up random archetypes from typealiases, and this changes the output in the RangeDiagnostics test. While we can debate if the new diagnostics are better or worse (I think it's either a wash, or slightly better) the reason they changed is because more in-depth diagnostic code is now executing, without breaking things randomly as before. I suspect this is a good thing.

…:RequirementSource::getMinimalConformanceSource Add test case for crash triggered in `swift::GenericSignatureBuilder::RequirementSource::getMinimalConformanceSource`. Current number of unresolved compiler crashers: 63 (5600 resolved) /cc @DougGregor - just wanted to let you know that this crasher caused an assertion failure for the assertion `nestedPAByName && "Didn't find the associated type we wanted"` added on 2017-03-23 by you in commit 8bd863e :-) Assertion failure in [`lib/AST/GenericSignatureBuilder.cpp (line 640)`](https://github.com/apple/swift/blob/f1d8f94b6d6b326dcaca369b719e9f397a1e380a/lib/AST/GenericSignatureBuilder.cpp#L640): ``` Assertion `nestedPAByName && "Didn't find the associated type we wanted"' failed. When executing: PotentialArchetype *replaceSelfWithPotentialArchetype(PotentialArchetype *, swift::Type) ``` Assertion context: ```c++ if (auto result = findNested(otherBasePA)) return result; }
