Description

[GlobalISel][AArch64] Select llvm.aarch64.crypto.sha1h

This was falling back and gives us a reason to create a selectIntrinsic function
which we would need eventually anyway. Update arm64-crypto.ll to show that we
correctly select it.

Also factor out the code for finding an intrinsic ID.

llvm-svn: 359501
