AMDGPU/GlobalISel Check for NoNaNsFPMath in isKnownNeverSNaN
Check for NoNaNsFPMath function attribute in isKnownNeverSNaN. Function attributes are in held in 'TargetMachine.Options'. Among other things, this allows selection of some patterns imported in D87351 since G_FCANONICALIZE is not generated when isKnownNeverSNaN returns true in lowerFMinNumMaxNum. However we notice some incorrect results since function attributes are not correctly written in TargetMachine.Options when next function is processed. Take a look at @v_test_no_global_nnans_med3_f32_pat0_srcmod0, it has "no-nans-fp-math"="false" but TargetMachine.Options still has it set to true since first function in test file had this attribute set to true. This will be fixed in D87511. Differential Revision: https://reviews.llvm.org/D87456
