[PATCH 0/2] Improvements of member pointer handling in ipa-prop.[ch]

[Martin Jambor]

Hi,

when I set out to replace the modified flag in ipa-prop.[ch] with
alias analysis queries and made myself a testcase I quickly realized
that the two pattern matching functions that identify C++ member
pointer calls and constant arguments very often fail when they really
shouldn't.

So I ended up with two patches for a more convenient review.  The
first patch improving those functions and the second one actually does
get rid off the modified flag.  Some additional details are in the
individual email messages.

Thanks,

Martin
