[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).

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] Recommit: "N64 static relocation model support" This patch makes one change to GOT handling and two changes to N64's relocation model handling. Furthermore, the jumptable encodings have been corrected for static N64. Big GOT handling is now done via a new SDNode MipsGotHi - this node is unconditionally lowered to an lui instruction. The first change to N64's relocation handling is the lifting of the restriction that N64 always uses PIC. Now it is possible to target static environments. The second change adds support for 64 bit symbols and enables them by default. Previously N64 had patterns for sym32 mode only. In this mode all symbols are assumed to have 32 bit addresses. sym32 mode support is selectable with attribute 'sym32'. A follow on patch for clang will add the necessary frontend parameter. This partially resolves PR/23485. Thanks to Brooks Davis for reporting the issue! This version corrects a "Conditional jump or move depends on uninitialised value(s)" error detected by valgrind present in the original commit.
