[AArch64][SVE] Add intrinsics for first-faulting gather loads
Summary:
The following intrinsics are added:
* @llvm.aarch64.sve.ldff1.gather
* @llvm.aarch64.sve.ldff1.gather.index
* @llvm.aarch64.sve.ldff1.gather_sxtw
* @llvm.aarch64.sve.ldff1.gather.uxtw
* @llvm.aarch64.sve.ldff1.gather_sxtw.index
* @llvm.aarch64.sve.ldff1.gather.uxtw.index
* @llvm.aarch64.sve.ldff1.gather.scalar.offset
Although this patch is quite substantial, the vast majority of the
implementation is just a 'copy & paste' of the implementation of regular
gather loads, including tests. There's only a handful of new
definitions:
* AArch64ISD nodes defined in AArch64ISelLowering.h (e.g. GLDFF1)
* Seleciton DAG Types in AArch64SVEInstrInfo.td (e.g.
AArch64ldff1_gather)
* intrinsics in IntrinsicsAArch64.td (e.g. aarch64_sve_ldff1_gather)
* Pseudo instructions in SVEInstrFormats.td to workaround the issue of
use-before-def for the FFR register.
