Log Message:
-----------
BYTECODE_HELPER_ID LLint opcodes need look up for wide versions.
https://bugs.webkit.org/show_bug.cgi?id=266294
rdar://119563251
Reviewed by Justin Michaud.
FOR_EACH_BYTECODE_HELPER_ID was mistakenly lumped in with
FOR_EACH_LLINT_NATIVE_HELPER, which
does not populate their entries in g_opcodeMapWide16 and g_opcodeMapWide32.
This patch fixes
that.
This was causing CLoop runs to crash on nullptr derefs on these non-initialized
entries.
