Ryan Houdek 2cab87fbd0 ThreadManager: Fix mmap usage to not take guest space 
SHM stats and CallRet stack was accidentally using system mmap which
means it would take VA space from the guest. Ensure it uses the
Allocator helpers so that doesn't happen.

Gives 32-bit guests 8-ish megabyte of VA space back.

Lioncache a16d4ff1f3 OpcodeDispatcher: Deduplicate in LEAOp/SMSWOp 
We can shorten a few lines here by just storing the op addr value
to a local variable.

Lioncache 305b1ecf2d OpcodeDispatcher: Default alignment parameters for store helpers 
Avoids actively doing this wonky thing where we're passing
iInvalid all over the place to mean variable alignment depending
on store element size or GPR size.

Makes using the API a little more visibly straightforward and makes
cases where alignment matters more explicit.

Ryan Houdek 45978474f3 Allocator: Name FEX's VMA regions for allocation 
Will allow external tools to track how much memory FEX allocates.
Necessary since we can't use traditional memory usage tools to track FEX
memory allocation independently of guest allocations. Plus most tools
like heaptrack hook allocation symbols, which break under jemalloc.

Using this information I can see with Steam loaded with my library that
FEX consumes ~825MB. Total process resident memory is 1204M, accounting
for around 379MB being used by steam itself. This is /relatively/ close
to my desktop running steam at around 261MB. There's a bit of variance
due to what Steam chooses to do at startup.

This tracking will be the first step towards seeing where our memory
usage is going.

Lioncache 0b238d942e Common/StringConv: std::stoull -> std::strtoull for enum handler

Ryan Houdek a499ad6404 IR: Implement two new IR ops 
rbit is useful in generic algorithms.
`MaskGenerateFromBitWidth` is only really useful for SSE4a, but

Lioncache 48c6acbc87 IR: Move RegisterAllocationPass forward decl to JITClass 
This isn't actually used anywhere in the IR header, so we can
move it to where it's actually used.

Now the IR interface header doesn't have anything related to the
independent passes in it.

Ryan Houdek 012c2ba851 IR: Fixes vector 64-bit binops 
We were only supporting operating size of 256-bit and 128-bit. These
also support 64-bit which wasn't wired up.

SSE4a will want to use 64-bit.

Lioncache a0c2ce0068 EnumUtils: Add define for default passthrough formatting 
Handles a normal case where printing an enum type as an integral value
is still desirable.

Mainly just a way to reduce boilerplate.
