Checks the new tslang (v0.0-pre-alpha93) and fixes the examples that couldn't run under the JIT.

The new tslang

• Everything compiles; 57/57 tests pass.
• JIT cache crash: with the JIT cache on (the default), a run that has to compile two or more modules crashes tslang with 0xC0000005, after writing the first module's object. Each crashing run caches one more module, so an example crashed on its first two runs: it, core/input_pass.ts and core/donut.ts are three modules.
  • Minimal repro: useslib.ts doing import { twice } from "./lib". It crashes from an empty cache and prints twice 42 on the next run, or with --jit-cache=false.
  • Workaround: run_jit.bat now passes --jit-cache=false. The README documents it, and that program arguments go after --.
  • Reported as TypeScriptCompiler#548.
• New warning: it now warns when a number is stored into a variable inferred as s32 from an integer literal. There were 36 sites:
  • 35 hold integers by construction (parseInt, Math.floor, Math.max of integers) and are now declared int. Same type as before; the warning is gone.
  • 1 was a real truncation: multithreading's checkFrame summed each pixel's fractional average into an integer. It is now a number.

JIT: missing symbols (16 examples)

Under the JIT, donut_interop.dll is all an example gets, and it held only core/donut_interop.cpp. These examples failed with JIT session error: Symbols not found:

Module	Examples
core/sdkmesh.cpp	bokeh, raytracing_ao, simple_pbr, mouse_cursor
core/meshlet_model.cpp	meshlet_render, meshlet_cull, meshlet_instancing, dynamic_lod
core/basis_transcoder.cpp	texture_compression_basisu, texture_compression_comparison
core/obj_model.cpp	sakura_forest_ser
core/paged_images.cpp	memory_management
core/video_player.cpp	video_texture
core/fast_block_compress.cpp	fast_block_compress
core/denoised_rtao.cpp (PBRT)	denoised_rtao
core/directx_collision.cpp	collision

The shared library now builds these modules in. It links basisu_transcoder, and on Windows delay-loads mfplat.dll as video_texture does. The normal executables are unchanged.

JIT: Agility SDK

Executables that need the Agility SDK runtime export D3D12SDKVersion/D3D12SDKPath (core/d3d12_agility_sdk.cpp). Under the JIT the process is tslang.exe, which has no such exports, so they got the system runtime. sakura_forest_ser failed with "Device doesn't support Shader Model 6.9".

The shared library, and only it, now applies bin/D3D12's runtime before the first device: ID3D12SDKConfiguration1::CreateDeviceFactory + ApplyToGlobalState. It only does this when the executable doesn't opt in itself.

Verification

• Symbols: every example's Donut_* references now resolve against the DLL's exports (887, up from 766).
• JIT runs: with the same arguments CTest uses, these pass their -test runs:
  • meshlet_render, meshlet_cull, meshlet_instancing, dynamic_lod and denoised_rtao (×3), on both dx12 and vk;
  • sakura_forest_ser, all 4 sort modes, on the Agility runtime 619;
  • memory_management, all 3 variants;
  • generic_programs and host_image_copy.
• Without a headless mode: bokeh, raytracing_ao, simple_pbr, mouse_cursor, collision, fast_block_compress, texture_compression_* and video_texture are covered by the symbol check only.
• Normal build: no warnings, 57/57 tests.
