  [CIR] Emit globals for declarations that force externally visible defs

CIRGenModule::emitGlobal reported NYI for forward declarations that
force an externally visible definition under C99 inline rules (inline
definition in the TU, then a later extern declaration). Classic
CodeGenModule already materializes these with GetOrCreateLLVMFunction;
wire the same path through getAddrOfFunction, including the AArch64
multiversion guard from OGCG.

This pattern shows up in SPEC CPU 2026 berkeley-abc `if.h` when
compiling `abcIf.c` for 729.abc_r / 829.abc_s (`If_CutCopy` at line
527).

Test: `inline-extern-force-codegen.c` with CIR, LLVM, and OGCG checks.
