A set of of small peepholes to improve the performance of new integers:

  • peepholes for comparisons with Int.Max
  • peepholes for some variants of cond_br
  • some overflow-check-removal improvements.

[sil-combine] Canonicalize boolean equality checks
315b2ab 
Convert i1_const != X to X != i1_const.
Convert i1_const == X to X == i1_const.

[sil-combine] Handle more patterns in cond_br conditions
616ef49 
Add the following peepholes:
cond_br(x == 0), t_label, f_label -> cond_br x, f_label, t_label
cond_br (x != 1), t_label, f_label -> cond_br x, f_label, t_label

[constant-propagation] Simplify comparisons with Int.max
2326cb7 
Make use of the following inequalities:
1) Int.max >= X, X <= Int.max are always true for any signed integer X
2) Int.max < X, X > Int.max are always false for any signed integer X
3) For any X of the same size as Int.max and any n>=1 , (X>>n) is always <= Int.max, that is (X>>n) <= Int.max and Int.max >= (X>>n) are always true.
     At the same time (X>>n) > Int.max and  Int.max < (X>>n) is always false.
4)  X < 0 is always false, if X is known to be a result of an unsigned operation with overflow checks enabled.
     X >= 0 is always true, if X is known to be a result of an unsigned operation with overflow checks enabled.

@swiftix thank you, and thanks especially for a solution that doesn't need to touch the standard library!
