It's not necessary to do rounding for alloca operations when the requested
alignment is equal to the stack alignment.

+; July 6, 2002 -- LLC Regression test
+; This test case checks if the integer CC register %xcc (or %ccr)
+; is correctly spilled. The code fragment came from function
+; MakeGraph in Olden-mst.
+; The original code made all comparisons with 0, so that the %xcc
+; register is not needed for the branch in the first basic block.
+; Replace 0 with 1 in the first comparson so that the
+; branch-on-register instruction cannot be used directly, i.e.,
+; the %xcc register is needed for the first branch.
+;
