[JSC] Add --traceWasmIPIntExecution option
https://bugs.webkit.org/show_bug.cgi?id=305238
rdar://167878555
Reviewed by Mark Lam.
This PR adds a simple per-opcode execution tracing to IPInt a la LLInt.
Like --traceLLIntExecution, this is controlled by both a compile time flag and
a runtime flag. Both LLINT_TRACING must be defined at compile time and
--traceWasmIPIntExecution=1 must be passed at runtime.
Example output:
<0x1080000e0> 0x1083c0188.wasm-function[0] / 0x16d2505a0: executing +0x0,
I32Const, pc = 0x10819aeb3, mc = 0x1083b00c0
