[JSC] Clean up baseline slow path

[JSC] Clean up baseline slow path
https://bugs.webkit.org/show_bug.cgi?id=178646

Reviewed by Saam Barati.

If the given op is just calling a slow path function, we should use DEFINE_SLOW_OP instead.
It is good since (1) we can reduce the manual emitting code and (2) it can clarify which
function is implemented as a slow path call. This patch is an attempt to reduce 32bit specific
code in baseline JIT.
