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
