cc1as: change AssemblerInvocation.Triple from std::string to llvm::Triple, matching upstream LLVM 22 and fixing deprecation warnings for lookupTarget, createMCRegInfo, createMCAsmInfo, and createMCSubtargetInfo. interp: always use ConstNamedStruct in rawValue.toLLVMValue instead of falling back to ConstStruct for unnamed structs. LLVM 22 uses anonymous identified struct types where previous versions used literal structs; ConstStruct creates a literal type that doesn't match, causing an "initializer type mismatch" panic for globals like fmt.ppFree. compileopts: add build-tag-guarded feature patching for pre-LLVM 20 (strip +bulk-memory-opt and +call-indirect-overlong from wasm features) and restructure into three files covering all LLVM version ranges. targets: strip redundant negative features from RISC-V target JSONs (esp32c3, esp32c6, fe310, k210, riscv-qemu, tkey). These ~190 negative features per target listed every extension LLVM knows about that the target doesn't use, but LLVM disables them by default. They became stale across LLVM versions, causing "not a recognized feature" warnings. Keep only positive features and -relax. Signed-off-by: deadprogram <ron@hybridgroup.com>
