MIPS64: Improve method invocation.

Improvements include:
- support for all kinds of method loads and static/direct calls
- 32-bit and 64-bit literals for the above and future work
- shorter instruction sequences for recursive static/direct calls
Also:
- include the MIPS64 dinsu instruction (missed earlier) and minor
  clean-up in the disassembler
- properly prefix constant names with 'k' in relative patcher tests

Test: test-art-host-gtest
Test: booted MIPS64 (with 2nd arch MIPS32R6) in QEMU
Test: "make -j1 ART_TEST_DEFAULT_COMPILER=false ART_TEST_OPTIMIZING=true
       ART_TEST_INTERPRETER=false ART_TEST_JIT=false
       ART_TEST_PIC_TEST=true test-art-target-run-test64"
