We need to pass the TargetMachine object to the InstPrinter if we are printing the alias of an InstAlias instead of the thing being aliased. Because we need to know the features that are valid for an InstAlias. This is part of a work-in-progress. llvm-svn: 127986

The tLDR et al instructions were emitting either a reg/reg or reg/imm instruction based on the t_addrmode_s# mode and what it returned. There is some obvious badness to this. In particular, it's hard to do MC-encoding when the instruction may change out from underneath you after the t_addrmode_s# variable is finally resolved. The solution is to revert a long-ago change that merged the reg/reg and reg/imm versions. There is the addition of several new addressing modes. They no longer have extraneous operands associated with them. I.e., if it's reg/reg we don't have to have a dummy zero immediate tacked on to the SDNode. There are some obvious cleanups here, which will happen shortly. llvm-svn: 121747

Add support to the ARM MC infrastructure to support mcr and friends.

Add instruction encoding for the Neon VMOV immediate instruction. This changes the machine instruction representation of the immediate value to be encoded into an integer with similar fields as the actual VMOV instruction. This makes things easier for the disassembler, since it can just stuff the bits into the immediate operand, but harder for the asm printer since it has to decode the value to be printed. Testcase for the encoding will follow later when MC has more support for ARM. llvm-svn: 105836
