hir_instr_c.h: 4 inline opcode predicates for BLME C-port (Phase 4.A batch 1)

SonicField · SonicField · commit 256984d4fd25 · 2026-04-27T01:21:03.000-07:00
Header-only change — 4 trivial static-inline opcode predicates needed
for builtin_load_method_elimination's pure-C port. Added next to the
existing hir_c_is_* family (after hir_c_is_replayable):

- hir_c_is_call_method        (HIR_OP_CallMethod)
- hir_c_is_load_method_super  (HIR_OP_LoadMethodSuper)
- hir_c_is_get_second_output  (HIR_OP_GetSecondOutput)
- hir_c_is_load_method_base   (3-way disjunction over LoadMethod /
                               LoadMethodCached / LoadModuleMethodCached;
                               C-side mirror of jit::hir::isLoadMethodBase
                               at hir.cpp:725)

No .c/.cpp changes; no behavior change. Phase 4.A pilot (theologian
invariant pre-audit 08:10:43Z + supervisor 08:14:58Z PROCEED on
header-only step).

Build: scripts/build_phoenix.sh --clean PASS (testkeeper 08:18:43Z +
08:20:37Z clarification — only this hir_instr_c.h delta in WT during
build; 4 unrelated mods stashed for isolation; clean ThinLTO; included
by 10+ jit/hir/*.c TUs which all compiled under C with the new
predicates in scope).
