[PATCH][X86] AVX512: Add non-temporal stores

[Demikhovsky, Elena]

Hi Adam,

I checked your encoding with XED:

+// CHECK: vmovntpd
+// CHECK: encoding: [0x62,0xf1,0xfd,0x48,0x2b,0x72,0x04]
+vmovntpd %zmm6, 4(%rdx)
+

xed -64 -d 62f1fd482b7204
62F1FD482B7204
ICLASS: VMOVNTPD   CATEGORY: DATAXFER   EXTENSION: AVX512EVEX  IFORM: VMOVNTPD_MEMf64_ZMMf64_AVX512   ISA_SET: AVX512F_512
SHORT: vmovntpd zmmword ptr [rdx+0x100], zmm6

I see a different displacement value. You should specify compressed displacement in these instructions EVEX_CD8..

Note that I followed the AVX2 convention here and didn't add LLVM intrinsics for stores.  These can be generated with the nontemporal hint on LLVM IR stores (see new test). The GCC builtins are lowered directly into nontemporal stores.
