Yet another Ping after returning from vacation ...

I've now split off two logically self-contained subparts of the patch into separate revisions to hopefully simplify review:

[PseudoSourceValue] New category to represent floating-point status
https://reviews.llvm.org/D52785

[MI] New flag mayAccessMemory
https://reviews.llvm.org/D52786

This patch now depends on both of those and will only be committed together with them (if approved).
