[ARM] MVE VPT Blocks A minor iteration on the MVE VPT Block pass to enable more efficient VPT Block code generation: consecutive VPT predicated statements, predicated on the same condition, will be placed within the same VPT Block. This essentially is also an exercise to write some more tests for the next step, which should be more generic also merging instructions when they are not consecutive.

[MIR][ARM] MachineOperand comments This adds infrastructure to print and parse MIR MachineOperand comments. The motivation for the ARM backend is to print condition code names instead of magic constants that are difficult to read (for human beings). For example, instead of this: dead renamable $r2, $cpsr = tEOR killed renamable $r2, renamable $r1, 14, $noreg t2Bcc %bb.4, 0, killed $cpsr we now print this: dead renamable $r2, $cpsr = tEOR killed renamable $r2, renamable $r1, 14 /* CC::always */, $noreg t2Bcc %bb.4, 0 /* CC:eq */, killed $cpsr This shows that MachineOperand comments are enclosed between /* and */. In this example, the EOR instruction is not conditionally executed (i.e. it is "always executed"), which is encoded by the 14 immediate machine operand. Thus, now this machine operand has /* CC::always */ as a comment. The 0 on the next conditional branch instruction represents the equal condition code, thus now this operand has /* CC:eq */ as a comment. As it is a comment, the MI lexer/parser completely ignores it. The benefit is that this keeps the change in the lexer extremely minimal and no target specific parsing needs to be done. The changes on the MIPrinter side are also minimal, as there is only one target hooks that is used to create the machine operand comments. Differential Revision: https://reviews.llvm.org/D74306
