  -----------
  [InlineAdvisor] Add -inline-replay-scope=<Function|Module> to control replay scope

The goal is to allow grafting an inline tree from Clang or GCC into a new compilation without affecting other functions. For GCC, we're doing this by extracting the inline tree from dwarf information and generating the equivalent remarks.

This allows easier side-by-side asm analysis and a trial way to see if a particular inlining setup provides benefits by itself.

Testing:
ninja check-all
