Remove arm_apcscc from the test files. It is the default and doing this matches what llvm-gcc and clang now produce. llvm-svn: 106221 2010-06-17 17:18:27 +02:00			`define void @t(i8* %a, ...) nounwind {`
Mass update to CodeGen tests to use CHECK-LABEL for labels corresponding to function definitions for more informative error messages. No functionality change and all updated tests passed locally.

[ARM] Refactor the prologue/epilogue emission to be more robust. This is the first step toward supporting shrink-wrapping for this target. The changes could be summarized by these items: - Expand the tail-call return as part of the expand pseudo pass. - Get rid of the assumptions that the epilogue is the exit block: * Do not assume which registers are free in the epilogue. (This indirectly improve the lowering of the code for the segmented stacks, see the test cases.) * Take into account that the basic block can be empty.
