[InstCombine] add tests for ext-of-bool + add/sub; NFC

We should choose one of these as canonical:

  %z = zext i1 %cmp to i32
  %r = sub i32 %x, %z
  =>
  %s = sext i1 %cmp to i32
  %r = add i32 %x, %s

The test comments assume that the zext form is better,
but we can adjust that if we decide to go the other way.

The LLVM Compiler Infrastructure

This directory and its subdirectories contain source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and runtime environments.
