Decode and SPIR-V emitter corrections this title's shaders need: image and
memory operand handling, scalar ALU forms, and the IR plumbing that goes with
them.
A shader the recompiler cannot translate is a gap in emulation, not a reason to
take the process down: skipping the draw or dispatch that wanted it costs some
rendering, while aborting costs the title.
CompileOptions gains non_fatal and CompileResult gains unsupported. With
non_fatal set, the three places the recompile path gives up - an opcode with no
IR translation, a CFG that will not build, and resource tracking that cannot
resolve a descriptor - record the failure and unwind rather than calling EXIT,
and Recompile returns a result marked unsupported. The caller skips that draw or
dispatch. Nothing changes when non_fatal is clear.
Marvel's Spider-Man: Miles Morales meets an untranslatable compute shader on its
third frame, so a strict build cannot pass the opening logo. Astro's Playroom is
also stopped by a shader today and reaches a later, different failure with this
in place.
A buffer load wrote its destination unconditionally, clobbering lanes the exec
mask had masked off. Select against the previous value so inactive lanes keep
what they held.
S_CMP_{EQ,LG}_U64 against a mask operand and zero is the idiom for 'are any
lanes live'. Treating it as a scalar compare loses the per-lane information, so
emit an actual ballot for that shape.
Decode the high-half D16 LDS read and route it through the existing unsigned-short load lowering. Represent the destination as a high-half partial write so the low 16 bits of the VGPR remain intact. Add captured-instruction decode coverage and a Vulkan execution regression that verifies the preserved half.

* fixed linux build
- added correct uint long translation
- replaced throw with non-constexpr function so that it fails in case of malformed table
* shader: remove redundant opcode table comment
* shader: use EXIT for invalid opcode tables
