[Alignment] Use llvm::Align in MachineFunction and TargetLowering - fixes mir parsing Summary: This catches malformed mir files which specify alignment as log2 instead of pow2. See https://reviews.llvm.org/D65945 for reference, This is patch is part of a series to introduce an Alignment type. See this thread for context: http://lists.llvm.org/pipermail/llvm-dev/2019-July/133851.html See this patch for the introduction of the type: https://reviews.llvm.org/D64790 Reviewers: courbet Subscribers: MatzeB, qcolombet, dschuff, arsenm, sdardis, nemanjai, jvesely, nhaehnle, hiraditya, kbarton, asb, rbar, johnrusso, simoncook, apazos, sabuasal, niosHD, jrtc27, MaskRay, zzheng, edward-jones, atanasyan, rogfer01, MartinMosbeck, brucehoult, the_o, PkmX, jocewei, jsji, Petar.Avramovic, asbirlea, s.egerton, pzheng, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D67433 llvm-svn: 371608

[ARM] Fold VCMP into VPT MVE has VPT instructions, which perform the duties of both a VCMP and a VPST in a single instruction, performing the compare and starting the VPT block in one. This teaches the MVEVPTBlockPass to fold them, searching back through the basicblock for a valid VCMP and creating the VPT from its operands. There are some changes to the VPT instructions to accommodate this, altering the order of the operands to match the VCMP better, and changing P0 register defs to be VPR defs, as is used in other places.
