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
