  Log Message:
  -----------
  [ModRef] Move ModRefInfo and FunctionModRefBehavior into IR (NFC)

This is in preparation for
https://discourse.llvm.org/t/rfc-unify-memory-effect-attributes/65579.
FunctionModRefBehavior will be used by attributes, and as such has
to be available in IR, not just Analysis.

  Log Message:
  -----------
  Revert "[FunctionAttrs] Make location classification more precise"

This reverts commit b05f5b90a12098660a4fc16da0b4d421ddfe14e2.

There are thread sanitizer buildbot failures in simple_stack.c.
I think that's because this ended up affecting the handling of
volatile accesses to allocas. Reverting for now.
