[mips] Explicitly select `mips32r2` CPU for test cases require 64-bit FPU. NFC Support for 64-bit coprocessors on a 32-bit architecture was added in `MIPS32 R2`. llvm-svn: 365507

[mips] Emit `.module softfloat` directive This change fixes crash on an assertion in case of using `soft float` ABI for mips32r6 target. llvm-svn: 354882

Mips.abiflags is a new implicitly generated section that will be present on all new modules. The section contains a versioned data structure which represents essentially information to allow a program loader to determine the requirements of the application. This patch implements mips.abiflags section and provides test cases for it. llvm-svn: 212519

; CHECK: .nan legacy
[mips] Do not emit '.module fp=...' unless we really need to. We now emit this value when we need to contradict the default value. This restores support for binutils 2.24. When a suitable binutils has been released we can resume unconditionally emitting .module directives. This is preferable to omitting the .module directives since the .module directives protect against, for example, accidentally assembling FP32 code with -mfp64 and producing an unusuable object. llvm-svn: 213548
