Ryan Houdek 03f63f99a8 FEXCore: Moves StringUtils to FEXCore headers 
Once gdbserver gets moved to the frontend this will need to be in the
includes.

Alyssa Rosenzweig 2a2619c0f5 IR: Add bit masking selects 
Add new synthetic condition codes that do an AND as their relational operator,
testing the result. This is 1 IR op for things like

  (A & B) == 0 ? C : D

This can translate to

  tst A, B
  csel A, B, eq

In the future, if A is the NZCV register and B is a supported immediate, eg

  (NZCV & 0x80000000) == 0 ? C : D

this will be able to translate to a single instruction with the appropriate
condition

  csel A, B, pl

but that needs RA support.

Ryan Houdek e4bb0df486 IR: Convert all Move+Atomic+ALU ops from implicit to explicit size 
The number of times the implicit size calculation in GPR operations has
bit us is immeasurable and was a mistake from the start of the project.
The vector based operations never had this problem since they were
explicitly sized for a long time now.

This converts the base IR operations to be explicitly sized, but adds
implicit sized helpers for the moment while we work on removing implicit
usage from the OpcodeDispatcher.

Should be NFC at this moment but it is a big enough change that I want
it in before the "real" work starts.

Alyssa Rosenzweig af21b8f3c7 Move External/FEXCore/ to FEXCore/ 
It is not an external component, and it makes paths needlessly long.
Ryan seemed amenable to this when we discussed on IRC earlier.
