[PATCH] Backport lto/alias testsuite fixes for darwin to gcc 4.5.1

[Jack Howarth]

  The attached patch backports r159700, r158929, r159837 and 
r159924 from trunk to gcc 4.5 branch which eliminate several
lto and alias related testsuite failures on darwin. Tested on
x86_64-apple-darwin10. Okay for gcc 4.5.1?
