[JSC] Make Boolean constructor fast
https://bugs.webkit.org/show_bug.cgi?id=252889
rdar://105873474
Reviewed by Tadeu Zagallo.
Make Boolean constructor to JSFunction to make call faster. Normally, it does
not matter to constructors since allocation is much slower,
but Boolean constructor is used for a normal call to enforce the result to
Boolean, and in this case, allocation does not happen.
With disabling DFG,
ToT
Patched
boolean-constructor 12.7293+-0.1106 ^
11.6629+-0.1843 ^ definitely 1.0914x faster
