…m modules When not performing codegen, we can strip the coverage-data-file and coverage-notes-file options to improve canonicalization. rdar://107443796 Differential Revision: https://reviews.llvm.org/D147282 (cherry picked from commit 758bca6)
Companion to https://reviews.llvm.org/D147282; when caching a PCH, remove the -coverage-data-file and -coverage-notes-file options. These paths cannot currently be prefix-mapped, because they are emitted into the binary for the coverage runtime to use. However, they have no effect on PCH, so remove them. rdar://107443796 (cherry picked from commit 0d086a5) (cherry picked from commit eb9236e)
Centralize the handling of prefix mapping options so that the driver is responsible for lowering `-fdepscan-prefix-map-sdk` and `-fdepscan-prefix-map-toolchain` to use `-fdepscan-prefix-map`, and all the tools take their prefix mappings from `FrontendOptions::PathPrefixMappings` instead of each having their own handling. This makes it easier for new code paths to use prefix mapping, since they get configuration "for free". cc1depscan[d] no longer needs special handling of these options at all, and in tests we just move to the driver or cc1 options. For clang-scan-deps it's move convenient to keep the command-line options, but implement them in the argument adjuster by adding the right driver options. rdar://106307646 (cherry picked from commit 5f5cf44)
