[erlang-patches] Print column numbers when compiling

As discussed with Tuncer Ayaz off-list, I added a test to error_SUITE checking
that column numbers are correctly included in warnings and errors messages.

I don't think this should be extensively tested but I maybe I could tweak
epp_SUITE and put all of its tests in a group and execute them with and
without the column option as it is already full of {Line, Column} locations
that could be tested, the column numbers are currently stripped in
messages_compare/1.

The following changes since commit 9bbda97f63ba4ee7cd58c266ee69af1059352189:

  Merge branch 'raimo/tools/remove-fprof-tuple-funs/OTP-10091' into maint (2012-05-23 16:15:58 +0200)
