- Implement asm parsing support for LDRSBT, LDRHT, LDRSHT and STRHT also fix the encoding of the later. - Add a new encoding bit to describe the index mode used in AM3. - Teach printAddrMode3Operand to check by the addressing mode which index mode to print. - Testcases. llvm-svn: 128832

ARM refactoring assembly parsing of memory address operands. Memory operand parsing is a bit haphazzard at the moment, in no small part due to the even more haphazzard representations of memory operands in the .td files. Start cleaning that all up, at least a bit. The addressing modes in the .td files will be being simplified to not be so monolithic, especially with regards to immediate vs. register offsets and post-indexed addressing. addrmode3 is on its way with this patch, for example. This patch is foundational to enable going back to smaller incremental patches for the individual memory referencing instructions themselves. It does just enough to get the basics in place and handle the "make check" regression tests we already have. Follow-up work will be fleshing out the details and adding more robust test cases for the individual instructions, starting with ARM mode and moving from there into Thumb and Thumb2. llvm-svn: 136845
