[WebGPU] Make wgslc and wgslfuzz distinct from each other
https://bugs.webkit.org/show_bug.cgi?id=259454 rdar://112798797 Reviewed by Mike Wyrzykowski. It would be useful to make the compiler and the fuzzer different executables for local development, so when the fuzzer finds a problem, you can feed that into the compiler to debug it. The way this works is: % set-webkit-configuration --debug --asan --libFuzzer % cd Source/WebGPU % make SCHEME=wgslfuzz % make SCHEME=wgslc % ASAN_OPTIONS=whatever DYLD_FRAMEWORK_PATH=/path/to/Products/Debug DYLD_LIBRARY_PATH=/path/to/Products/Debug /path/to/Products/Debug/wgslfuzz % ASAN_OPTIONS=whatever DYLD_FRAMEWORK_PATH=/path/to/Products/Debug DYLD_LIBRARY_PATH=/path/to/Products/Debug /path/to/Products/Debug/wgslc * Source/WebGPU/Configurations/wgslfuzz.xcconfig: Added. * Source/WebGPU/WGSL/wgslc.cpp: (main): (LLVMFuzzerTestOneInput): Deleted. * Source/WebGPU/WGSL/wgslfuzz.cpp: Added. (LLVMFuzzerTestOneInput): * Source/WebGPU/WebGPU.xcodeproj/project.pbxproj: * Source/WebGPU/WebGPU.xcodeproj/xcshareddata/xcschemes/wgslfuzz.xcscheme: Added.
