Port DFG JIT to traditional ARM
https://bugs.webkit.org/show_bug.cgi?id=90198
Reviewed by Filip Pizlo.
Source/JavaScriptCore:
This patch contains the macro assembler part of the
DFG JIT support on ARM systems with fixed 32 bit instruction
width. A large amount of old code was refactored, and the ARMv4
or lower support is removed from the macro assembler.
Sunspider is improved by 8%, and V8 is 92%.
