Fix LowerBlockAddress to produce instructions with the correct relocation types for N32 ABI and update test case. llvm-svn: 154031

Move the Mips target to storing the ABI in the TargetMachine rather than on MipsSubtargetInfo. This required a bit of massaging in the MC level to handle this since MC is a) largely a collection of disparate classes with no hierarchy, and b) there's no overarching equivalent to the TargetMachine, instead only the subtarget via MCSubtargetInfo (which is the base class of TargetSubtargetInfo). We're now storing the ABI in both the TargetMachine level and in the MC level because the AsmParser and the TargetStreamer both need to know what ABI we have to parse assembly and emit objects. The target streamer has a pointer to the one in the asm parser and is updated when the asm parser is created. This is fragile as the FIXME comment notes, but shouldn't be a problem in practice since we always create an asm parser before attempting to emit object code via the assembler. The TargetMachine now contains the ABI so that the DataLayout can be constructed dependent upon ABI. All testcases have been updated to use the -target-abi command line flag so that we can set the ABI without using a subtarget feature. Should be no change visible externally here. llvm-svn: 227102

[Mips] Adjust float ABI settings in case of MIPS16 mode. Hard float for mips16 means essentially to compile as soft float but to use a runtime library for soft float that is written with native mips32 floating point instructions (those runtime routines run in mips32 hard float mode). The patch reviewed by Reed Kotler. llvm-svn: 195123

Revert r237789 - [mips] The naming convention for private labels is ABI dependant. It works, but I've noticed that I missed several callers of createMCAsmInfo() and many don't have a TargetMachine to provide. llvm-svn: 237792

[mips] Correct label prefixes for N32 and N64. Summary: N32 and N64 follow the standard ELF conventions (.L) whereas O32 uses its own ($). This fixes the majority of object differences between -fintegrated-as and -fno-integrated-as.
