[JSC] Micro-optimize stricteq in Baseline JIT with bitwise-comparable
constants
https://bugs.webkit.org/show_bug.cgi?id=272948
rdar://126726702
Reviewed by Keith Miller.
We observed stricteq with true / false / void 0 / null cases in the wild, so
let's have some optimized code generation even in baseline JIT since it is
simple.
