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.

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.
