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.

Maintain a list of free code blocks, and allocate new blocks from the list rather than evicting at random.
...
Also maintain a list of memory pages with dirty code blocks that can be evicted. This allows the recompiler to evict dirty blocks in preference to freeing usable blocks when the free list is empty.
Increase the number of available code blocks on x86.
Increase the non-ARM code allocator memory to 128 MB.
This reduces the amount of code block churning when running software with a lot of code, eg Windows XP.
