Set useful flags for vector imm setting instructions

Vector imm setting instructions like XXLXORz/XXLXORspz/XXLXORdpz
Should behave like LI8.

We should set corresponding flags to allow rematerialization and other
opts in LICM, RA, Scheduling etc.

[PowerPC] Do not produce invalid CTR loop with an FRem

An FRem instruction inside a loop should prevent the loop from being converted
into a CTR loop since this is not an operation that is legal on any PPC
subtarget. This will always be a call to a library function which means the
loop will be invalid if this instruction is in the body.

Fixes PR36292.
