...
if the destination register won't be immediately used again.

Rework self modifying code handling.
...
Code blocks now have a varying level of granularity in the page and dirty masks.
Most blocks have 64-byte granularity, but blocks that are repeatedly modified
drop to 1-byte granularity. This reduces the maximum size of the affected block
significantly, but reduces recompilation due to data located too close to code.
If the block is still marked as dirty, then it is recompiled without any
immediate instruction parameters being baked into the recompiled code, instead
being fetched from the RAM array as needed. This severely reduces recompilation
rates on some SMC-heavy games, eg Duke Nukem 3D, System Shock, Screamer etc,
giving a major speedup.

Add new codegen memory allocator. This allows the recompiler to allocate memory from a central pool as required. This central pool is by default 64 MB on x86, x86-64 and ARMv8, and 32 MB on ARMv7.
...
The current design does not allow for ARMv8 literal pools, therefore these have been removed.
