FTL should build on ARM64
​https://bugs.webkit.org/show_bug.cgi?id=129010

Reviewed by Sam Weinig.

• disassembler/X86Disassembler.cpp: Just because we have the LLVM disassembler doesn't mean we're on X86.
• ftl/FTLLocation.cpp: DWARF parsing for ARM64 is super easy.

(JSC::FTL::Location::isGPR):
(JSC::FTL::Location::gpr):
(JSC::FTL::Location::isFPR):
(JSC::FTL::Location::fpr):
(JSC::FTL::Location::restoreInto): This function wasn't even X86-specific to begin with so move it out of the #if stuff.

• ftl/FTLUnwindInfo.cpp: They're called q not d.

(JSC::FTL::UnwindInfo::parse):

• jit/GPRInfo.h:

(JSC::GPRInfo::toArgumentRegister): Add this method; we alraedy had it on X86.
