[Patch] testsuite/gdb.pascal new testcase integer.exp

 I committed this 
as pascal language maintainer.

  For gpc mailing list mainly:
I had to add to XFAIL for gpc
because of the buggy line information.
  I used an old gpc 
gpc 20050331, based on gcc-3.4.4 (cygming special, gdc 0.12, using dmd
0.125)
but this is the official cygwin distro of gpc.

  Do newer gpc binaries give better results?
