  [JSC] Add emitGetVirtualRegisters which loads multiple registers via ldp if possible
https://bugs.webkit.org/show_bug.cgi?id=261399
rdar://115274448

Reviewed by Keith Miller.

This patch adds emitGetVirtualRegisters, which optimizes multiple loads from stack in baseline JIT.
This uses ldp if possible in 64bit platform. We also add dumpBaselineDisassembly option to dump
disassembly only for Baseline for testing.
