Change and simplify the way that Memcheck instruments saturating
narrowing operations. The previous scheme was simply wrong and could
cause false negatives, by causing some narrowing operations to have a
defined output even when the inputs are undefined. This was what
#279698 reported. This patch is a fix for that bug.

This patch by Philippe Waroquiers, philippe.waroquiers@skynet.be
replaces r12124. His analysis of the testcase failure:
I think I understand what is happening: even if the ptrace invoker functionality
is not needed, the timeout to invoke might expire, which then leads
to a message produced by vgdb if ptrace is restricted by the kernel.
I think the best way to fix this is to add the option --max-invoke-ms=0 to vgdb.

Improve filtering of backtrace noise in the memcheck bucket

New file filter_memcheck to do the work.
There is a bit of a ripple here as filter_memcheck requires
command line arguments to be passed in. So all users of
filter_memcheck (direct or indirect) were updated as well.
filter_stderr was simplified as was filter_libc.

Rename testcase from execve to execve1.
The reason is that the point of failure is in glibc
in a file named execve.c The backtrace filtering
(which is filename based) cannot distinguish the
two execve.c file names. Renaming the testcsae does the
trick.
