Unfortunately this patch regressed a bunch of guality tests, diff on
testsuite_summary shows on x86_64-linux:
 XPASS: gcc.dg/guality/guality.c  -O3 -g  execution test
 XPASS: gcc.dg/guality/guality.c  -Os  execution test

 XPASS: gcc.dg/struct/wo_prof_array_through_pointer.c scan-ipa-dump ipa_struct_reorg "Number of structures to transform is 1"
and similarly for i686-linux.

For inline-params.c the detailed new state is:
FAIL: b is optimized away, expected 3003
PASS: ab is 6296384
PASS: ac is 6296388
PASS: msg is 4197837
FAIL: 3 PASS, 1 FAIL, 0 UNRESOLVED
XFAIL: gcc.dg/guality/inline-params.c  -O1  execution test
where it used to be:
PASS: b is 3003
PASS: ab is 6296384
PASS: ac is 6296388
PASS: msg is 4197837
PASS: 4 PASS, 0 FAIL, 0 UNRESOLVED
XPASS: gcc.dg/guality/inline-params.c  -O1  execution test
and for pr41616-1.c newly:
FAIL: b is optimized away, expected -1
PASS: b is 1
FAIL: 1 PASS, 1 FAIL, 0 UNRESOLVED
XFAIL: gcc.dg/guality/pr41616-1.c  -O1  execution test
from:
PASS: b is -1
PASS: b is 1
PASS: 2 PASS, 0 FAIL, 0 UNRESOLVED
XPASS: gcc.dg/guality/pr41616-1.c  -O1  execution test
