x86_64: JNI compiler

Passed all tests from jni_compiler_test and art/test on host with jni_copiler.
Incoming argument spill is enabled, entry_spills refactored. Now each entry spill
contains data type size (4 or 8) and offset which should be used for spill.
Assembler REX support implemented in opcodes used in JNI compiler.
Please note, JNI compiler is not enabled by default yet (see compiler_driver.cc:1875).
