AArch64: Jni compiler fixes

This patch fixes some of the issues with the ARM64 assembler and JNI
compiler.

The JNI compiler is not enabled by default, yet. To enable, change
line 1884 in compiler/driver/compiler_driver.cc, removing kArm64 from
the GenericJNI list.

The compiler passes all tests in jni_compiler_test.

Also change the common_compiler_test instruction-set-features logic.
We allow tests when the build-time features are a subset of the
runtime features.

Dex2oat cross-compiling is now working. A 32b version of dex2oat should
be able to compile correctly.

Use trampolines for calls to helpers

This is an ARM specific optimization to the compiler
that uses trampoline islands to make calls to runtime
helper functions.  The intention is to reduce the size
of the generated code (by 2 bytes per call) without
affecting performance.

By default this is on when generating an OAT file.  It is
off when compiling to memory.

To switch this off in dex2oat, use the command line option:
--no-helper-trampolines

Enhances disassembler to print the trampoline entry on the
BL instruction like this:
