Create sema_test.zig with:
- InternPool unit tests: pre-interned types/values, ipTypeOf,
ipIntern deduplication, new key interning, vector/pointer types
- Sema smoke tests: empty source and "const x = 0;" through
full C pipeline (parse → astgen → sema) without crashing
Wire sema_test.zig into test_all.zig.

Split cppcheck into per-file checks (warning,style,performance,portability)
and a combined unusedFunction check across all C files. Remove dead code
(addExtraU32, rvalueDiscard, wipMembersNextDecl, wipMembersBodiesAppend,
findNextContainerMember, NodeContainerField). Wire up zig0Run to actually
call astParse/astGen and print stats, eliminating unusedFunction warnings
for the public API.

Replace parser's fail() and astgen's flag-only SET_ERROR(ag) with a
single SET_ERROR(ctx, msg) macro in common.h that stores the error
message in ctx->err_buf and sets ctx->has_compile_errors. Both Parser
and AstGenCtx now carry the same err_buf[ERR_BUF_SIZE] field.

- Add warn() for non-fatal parse errors (like Zig's Parse.warn)
- Implement finishAssignDestructureExpr for destructuring assignments
- Use parseBlockExpr instead of parseBlock in for/while statement bodies
- Use parseSingleAssignExpr in switch prongs
- Enable x86_64/CodeGen.zig corpus entry

The @unionInit handler in builtinCallMultiArg was propagating the parent's
result info context (e.g. RI_CTX_RETURN) to the init value expression.
Upstream Zig creates a fresh ResultInfo with .ctx = .none. This caused
call flags mismatch (pop_error_return_trace) in return expressions.

rlBuiltinCall was always returning false (not consuming result location).
The Zig reference marks @frameAddress as consuming the RL (workaround for
llvm/llvm-project#68409), which affects declaration codegen path (pointer
vs value based). Match the upstream behavior.

The AST_NODE_CONTAINER_FIELD case in structDeclInner had an incorrect guard
`if (nd.rhs != 0)` before reading align/value from extra_data. Since rhs is
an extra_data index (not a node), 0 is a valid index. Removing the guard
fixes 3-5 missing instructions in files where the first extra_data entry
happens to be a container_field's align+value.
Also fix clang-format: addBuiltinValue arg wrapping, for-loop semicolons.

Upgrade decimal_float_fits_f64() to use 128-bit integer arithmetic for the
algebraic round-trip test, handling mantissas up to ~38 significant digits.
This fixes float128-vs-float tag mismatches for values that fit in 128-bit
mantissa but overflow 64-bit.
Newly enabled: gpu, memmove, mulf3, udivmodei4, udivmod, scalar, ff,
p256_64, p256_scalar_64, p384_64, p384_scalar_64, secp256k1_64,
secp256k1_scalar_64, sha2, sha3, Decompress, testing, log10, log2, log,
rem_pio2f, rem_pio2_large, rem_pio2.

decimal_float_fits_f64() incorrectly returned true when a non-zero mantissa
(that had overflowed uint64_t) was converted to 0.0 by strtod. These values
do not fit in f64 and need f128 representation.

Fix strtod underflow/overflow edge cases in decimal_float_fits_f64.
Enables 707 files across lib/std/, lib/compiler_rt/, src/, and more.

Define named constants for the three categories of optional sentinel
values, matching their Zig counterparts (?TokenIndex null,
?Node.Index null, Zir.Inst.OptionalIndex .none). This makes intent
explicit and prevents sentinel/zero confusion bugs like the one
fixed in 455967af.
