[JSC] Combine FTL code generation into one
https://bugs.webkit.org/show_bug.cgi?id=270684
rdar://124259821
Reviewed by Justin Michaud.
This patch simplifies FTL code generation. Previously we were always generating
two codes, one for normal code and one for arity check etc.
But just generating both into one is easy and simple. This patch cleans up
around it and use of LinkBuffer / AssemblerData etc. gets simplified.
Originally we were doing so since FTL part is generated by LLVM, and we
generate arity check as a separate code, but now both are generated by JSC's
JIT compiler. So we do not need to separate them.
