[opaque pointer type] Add textual IR support for explicit type parameter to getelementptr instruction One of several parallel first steps to remove the target type of pointers, replacing them with a single opaque pointer type. This adds an explicit type parameter to the gep instruction so that when the first parameter becomes an opaque pointer type, the type to gep through is still available to the instructions. * This doesn't modify gep operators, only instructions (operators will be handled separately) * Textual IR changes only. Bitcode (including upgrade) and changing the in-memory representation will be in separate changes. * geps of vectors are transformed as: getelementptr <4 x float*> %x, ... ->getelementptr float, <4 x float*> %x, ... Then, once the opaque pointer type is introduced, this will ultimately look like: getelementptr float, <4 x ptr> %x with the unambiguous interpretation that it is a vector of pointers to float. * address spaces remain on the pointer, not the type: getelementptr float addrspace(1)* %x ->getelementptr float, float addrspace(1)* %x Then, eventually: getelementptr float, ptr addrspace(1) %x Importantly, the massive amount of test case churn has been automated by same crappy python code.

[ARM] Fix codegen for VLD3/VLD4/VST3/VST4 with WB Code generation of VLD3, VLD4, VST3 and VST4 with register writeback is broken due to 2 separate bugs: 1) VLD1d64TPseudoWB_register and VLD1d64QPseudoWB_register are missing rules to expand them to non pseudo MIR. These are selected for ARMISD::VLD3_UPD/VLD4_UPD with v1i64 vectors in SelectVLD. 2) Selection of the right VLD/VST instruction is broken for load and store of 3 and 4 v1i64 vectors. SelectVLD and SelectVST are called with MIR opcode for fixed writeback (ie increment is access size) and call getVLDSTRegisterUpdateOpcode() to select an opcode with register writeback if base register update is of a different size. Since getVLDSTRegisterUpdateOpcode() only knows about VLD1/VLD2/VST1/VST2 the call is currently conditional on the number of element in the vector. However, VLD1/VST1 is selected by SelectVLD/SelectVST's caller for load and stores of 3 or 4 v1i64 vectors. Therefore the opcode is not updated which later lead to a fixed writeback instruction being constructed with an extra operand for the register writeback. This patch addresses the two issues as follows: - it adds the necessary mapping from VLD1d64TPseudoWB_register and VLD1d64QPseudoWB_register to VLD1d64Twb_register and VLD1d64Qwb_register respectively. Like for the existing _fixed variants, the cost of these is bumped for unaligned access. - it changes the logic in SelectVLD and SelectVSD to call isVLDfixed and isVSTfixed respectively to decide whether the opcode should be updated. It also reworks the logic and comments for pushing the writeback offset operand and r0 operand to clarify the logic: writeback offset needs to be pushed if it's a register writeback, r0 needs to be pushed if not and the instruction is a VLD1/VLD2/VST1/VST2.
