Thumb2 and ARM add/subtract with carry fixes. Fixes Thumb2 ADCS and SBCS lowering: <rdar://problem/9275821>. t2ADCS/t2SBCS are now pseudo instructions, consistent with ARM, so the assembly printer correctly prints the 's' suffix. Fixes Thumb2 adde -> SBC matching to check for live/dead carry flags. Fixes the internal ARM machine opcode mnemonic for ADCS/SBCS. Fixes ARM SBC lowering to check for live carry (potential bug). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@130048 91177308-0d34-0410-b5e6-96231b3b80d8 2011-04-23 03:55:32 +00:00			`; RUN: llc < %s -march=thumb -mattr=+thumb2 -mattr=+32bit \| FileCheck %s`
