fcae323a88 Arch-abstraction: 
- move LDT stuff out of core, into x86-linux specific stuff.  Some of it
  (VG_(do_useseg)()?) may be really x86-specific, rather than
  x86/linux-specific, but that can be fixed later if it's really shared with
  another OS.

ce3c7200a7 Fix for bug 91162: cope with jumps to bogus addresses when there is a SEGV 
signal handler present -- previously, Valgrind would abort unnecessarily on
this case.

Added a regression test for it.

588711ca62 More fixes for stabs generated by the GNAT compiler. This patch 
allows negative offsets in structure member definitions as well as
improving the previous fix for names that are declared as both struct
tags and typedefs.

is a regular file and fail with EINVAL if it is not.

actual problem reported in that bug.

ca05bfd7ec The fix for bug 85811 added decoding of many extra negative type 
numbers in stabs and also removed the expectation of a trailing
semicolon after the type number as gcc didn't seem to be putting
one in. It seems that older gcc's do add one however, so we now
skip one if it is there.
