MIPS32R6: Improve PC-relative string/class loads and invokes.
Use PC-relative addressing on MIPS32R6 instead of
HMipsDexCacheArraysBase and allow such PC-relative
addressing in presence of irreducible loops.
Also save a couple of instructions when handling
string and class loads from bss.
Test: test-art-host-gtest
Test: booted MIPS32R2 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-test"
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-test32"

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

MIPS32: Improve method invocation
Improvements include:
- CodeGeneratorMIPS::GenerateStaticOrDirectCall() supports:
- MethodLoadKind::kDirectAddressWithFixup (via literals)
- CodePtrLocation::kCallDirectWithFixup (via literals)
- MethodLoadKind::kDexCachePcRelative
- 32-bit literals to support the above (not ready for general-
purpose applications yet because RA is not saved in leaf
methods, but is clobbered on MIPS32R2 when simulating
PC-relative addressing (MIPS32R6 is OK because it has
PC-relative addressing with the lwpc instruction))
- shorter instruction sequences for recursive static/direct
calls
Tested:
- test-art-host-gtest
- test-art-target-gtest and test-art-target-run-test-optimizing on:
- MIPS32R2 QEMU
- CI20 board
- MIPS32R6 (2nd arch) QEMU
