Ryan Houdek 753d0ede6c FEXCore: Reclaimable thread pool allocator 
Creates a pool allocator for OpcodeDispatcher and IRCompaction that
shares memory allocations between threads in a pool and supports
reclaiming stale allocations from participating threads.

A thread will use a heuristic to keep its claimed memory allocation
around if it is allocating a lot of code. If it slows down then it will
start putting the memory allocation back in to the thread pool.

Additionally if the allocation has been "disowned" and gone to sleep
while still retaining the allocation, then another thread can inspect
 these stale allocations and reclaim it from the idling thread. Saving
further memory.

This needs some more work and cleanup but this is an interesting concept
that saves a decent amount of memory even in a basic test.

Causes teeworlds' title screen to go from 754MB to 599MB in my simple
test. 79.4% the memory usage is a good start.

Ryan Houdek f6a74a710d FEXBash: Set PS1 to make it more obvious when running under FEX 
This requires us to pass in --no-rc to bash since otherwise PS1 gets
overwritten by shell variables and nothing happens.

Which this is fine for the common use case of just wanting to run a
basic bash script under emulation.

Ryan Houdek 72e82d0304 Linux: Fixes 32-bit mmap 
This went unnoticed for so long since most applications are new enough
to use mmap2 instead of mmap.
This was just completely broken.

Fixes #1630

Ryan Houdek 52292e5f7e Linux: Fixes MAP_32BIT supported range 
I accidentally committed a 32-bit range that was significantly smaller
than what it should be.
While the minimal range worked for simple cases, it didn't work for
anything complex.
Give it the full range it needs.

Fixes #1600

Ryan Houdek 4cb6918506 Change page define usages over to self-defined 
In the case of an AArch64 builder is using 16kb or 64kb pages like is
common on servers then it would fail to compile, even if the resulting
application would only ever run on 4k page hosts.

Resolve this by removing the build check and hardcoding 4kb pages for
each of our uses. We still require 4kb pages to run, so this mostly just
removes the weirdness where it is 16kb builder + 4k runner. Would have
broken some of our assumptions when running.

Ryan Houdek 1f835ea1f4 LinuxSyscalls: Fixes semid and ipc types 
Newer headers redefine semid_ds and ipc_perm as semid64_ds and
