Split off from D81699 <https://reviews.llvm.org/D81699>

  Excludes `__sanitizer_unaligned_{load,store}` functions from checks.
  This is because they absolutely expect shadows passed over TLS.
  
  Adds lit configuration to be able to test MSAN's interaction
  with widespread eager checking due to clang emitting noundef attrs.
  
  Additionally introduces tests for:
  - Bitfield handling
  - Different sized function parameters
  - MSAN and struct padding (when passing structs by value)
