gcc46-pr46401.patch
Untested fix.
No point tracking CALL_EXPRs that aren't ECF_CONST (because then
operand_equal_p fails anyway) nor STRING_CSTs (which can't be written into).
That said, -Wsequence-point algorithm is still quadratic (certainly in used
memory, and at least quadratic in compilation time).
