Remove `NoNaNsFPMath` by using `PatFrag`, we should only use `nnan`. Duplicate tests in `CodeGen/Mips/llvm-ir/nan-fp-attr.ll` are removed.

; Check that abs.[ds] is only selected for mips32r6 or mips64r6 when no
|
|
; additional options are passed. For revisions prior mips32r6 and mips64r6,
|
|
; abs.[ds] does not generate the correct result when working with NaNs, and
|
|
; should be explicitly enabled with nnan flag or +abs2008 options.
|
|
|
|
; In 1985 mode, abs.[ds] are arithmetic (i.e. they raise invalid operation
|
|
; exceptions when given NaN's). In 2008 mode, they are non-arithmetic (i.e.
|
|
; they are copies and don't raise any exceptions).
