agra 10f4137cbd feat(asm): symbol operands ("s") — direct call/branch to a function
A `"s"` input operand feeds a function/global symbol; the template's
%[name] emits the platform-mangled name, so `bl %[fn]` / `call %[fn]`
branches DIRECTLY to it (PC-relative, no register load — one fewer
indirection than register-indirect `blr`).

Lowering: an `"s"` input lowers its RHS normally (a function name →
`ptr @fn`); the rejection added last commit is removed. Emit: a symbol
operand is passed with its OWN llvm type (LLVMTypeOf) and no coercion —
the function value is a `ptr`, and the old coerce-to-register-int path
mistyped it and failed the verifier. New asmIsSymbol helper.

Verified on aarch64: examples/1656 (sx → asm → bl _cb → sx → 42); the
emitted asm is a direct `bl <_cb>` (objdump-confirmed), IR constraint
`...,s,...`(ptr @cb). Flipped 1656 from the rejection lock to a runnable
aarch64 example. zig build test green (665 corpus, 446 unit).
