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

+; RUN: llvm-upgrade < %s | llvm-as | llc
+
+;; Date: May 28, 2003.
+;; From: test/Programs/MultiSource/Olden-perimeter/maketree.c
+;; Function: int CheckOutside(int x, int y)
+;;
+;; Note: The .ll code below for this regression test has identical
+;; behavior to the above function up to the error, but then prints
+;; true/false on the two branches.
+;;
+;; Error: llc generates a branch-on-xcc instead of branch-on-icc, which
+;; is wrong because the value being compared (int euclid = x*x + y*y)
+;; overflows, so that the 64-bit and 32-bit compares are not equal.
