X86: Resolve a long standing FIXME and properly isel pextr[bw].
Generalize the AArch64 .td nodes for AssertZext and AssertSext. Use them to match the relevant pextr store instructions. The test widen_load-2.ll requires a slight change because with the stores gone, the remaining instructions are scheduled in a different order. Add test cases for SSE4 and AVX variants. Resolves rdar://13414672. Patch by Adam Nemet <anemet@apple.com>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@200957 91177308-0d34-0410-b5e6-96231b3b80d8
