[mips] Add initial support for NaN2008 in the back-end. This is so that EF_MIPS_NAN2008 is set if we are using IEEE 754-2008 NaN encoding (-mnan=2008). This patch also adds support for parsing '.nan legacy' and '.nan 2008' assembly directives. The handling of these directives should match GAS' behaviour i.e., the last directive in use sets the ELF header bit (EF_MIPS_NAN2008).

; ### N32 ABI ###
; RUN: llc -filetype=asm -mtriple mips64-unknown-linux -mcpu=mips64 \
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] Switch to the `.text` section after emitting asm file preamble Now the last `.section` directive in the MIPS asm file preamble is the `.section .mdebug.abi`. If assembler code injected for example by the LLVM `module asm` or the C ` __asm` directives do not contain explicit switching to the `.text` section it goes to the `.mdebug.abi` section. It might be unexpected to the user and in fact for example breaks building some existing code like FreeBSD libc [1]. The patch forces switching to the `.text` section after emitting MIPS assembler file preamble. [1] https://bugs.llvm.org/show_bug.cgi?id=43119 Fix PR43119.
