LTO profiled-bootstrap revals:

/space/rguenther/src/svn/trunk/gcc/reginfo.c: In function 'reg_scan':
/space/rguenther/src/svn/trunk/gcc/reginfo.c:1015:0: error: location references
block not in block tree
 reg_scan (rtx f, unsigned int nregs ATTRIBUTE_UNUSED)
 ^
"ee"
fmt_351 = "ee";

/space/rguenther/src/svn/trunk/gcc/reginfo.c:1015:0: internal compiler error:
verify_gimple failed

this is a &STRING_CST node.  Needs to be tracked down ... more IPA stuff needs
to use copy_tree_without_location.
