nasty commit with a bunch of test code left in, will clean up and pr

Remove the logger_ != nullptr check from shouldlog, it will nearly always be true except on initialization and gets checked later anyway, this shrinks the size of the generated code for some
Select specialized vastcpy for current cpu, for now only have paths for MOVDIR64B and generic avx1
Add XE_UNLIKELY/LIKELY if, they map better to the c++ unlikely/likely attributes which we will need to use soon
Finished reimplementing STVL/STVR/LVL/LVR as their own opcodes. we now generate far less code for these instructions. this also means optimization passes can be written to simplify/remove/replace these instructions in some cases. Found that a good deal of the X86 we were emitting for these instructions was dead code or redundant.
the reduction in generated HIR/x86 should help a lot with compilation times and make function precompilation more feasible as a default

Don't static assert in default prefetch impl, in c++20 the assertion will be triggered even without an instantiation
Reorder some if/else to prod msvc into ordering the branches optimally. it somewhat worked...
Added some notes about which opcodes should be removed/refactored
Dispatch in WriteRegister via vector compares for the bounds. still not very optimal, we ought to be checking whether any register in a range may be special
A lot of work on trying to optimize writeregister, moved wraparound path into a noinline function based on profiling info
Hoist the IsUcodeAnalyzed check out of AnalyzeShader, instead check it before each call. Profiler recorded many hits in the stack frame setup of the function, but none in the actual body of it, so the check is often true but the stack frame setup is run unconditionally
Pre-check whether we're about to write a single register from a ring
Replace more jump tables from draw_util/texture_info with popcnt based sparse indexing/bit tables/shuffle lookups
Place the GPU register file on its own VAD/virtual allocation, it is no longer a member of graphics system
