  Log Message:
  -----------
  [sanitizer][asan][msvc] Teach GetInstructionSize about many instructions that appear in MSVC generated code. (#69490)

MSVC can sometimes generate instructions in function prologues that asan
previously didn't know the size of. This teaches asan those sizes. This isn't
super useful for using ASAN with non-msvc compilers, but it does stand alone.
