exposed by scheduling changes caused by commit vg_scheduler.c rev 1.70.
We cannot simply pass the __attr pointer to the child, since it could
point to stuff on the parent's stack, which might not exist by the time
the child looked at it. Prior to scheduler.c rev 1.70 the child would
have been scheduled as soon as created, so the access was made before the
parent could clear the stuff from its stack. From rev 1.70 and after
the parent continues after creating the child, causing invalid stack
accesses when the child finally runs.

into one. This can change the scheduling a bit since the policy of
running the same thread after the request if it is possible now applies
to _all_ requests.

fix a minor error, but basically no significant changes.
- Disable debug info printing entirely in addLineInfo.

handler, but in the interval between the signal arriving and it being
delivered to the client, the handler is removed.

seems to lead to a portability swamp. As a result, remove autoconf
check for <asm/atomic.h>. Replace all this junk with
VKI_SIZEOF_STRUCT_MODULE (== 96) since that's all I ever wanted to
know in the first place.

- fixed a bug that was breaking the --threshold option.
vg_cachesim.c:
- fixed a bug that meant instructions that didn't have a line number in the
debug info were being written in cachegrind.out with whatever was the
last known line number. Now using 0.

automatic cache configuration detection using the CPUID instruction.
This can be overridden from the command-line if necessary.
vg_include.h:
- added the cache_t type and UNDEFINED_CACHE macro
- added command line args (of type cache_t) allowing manual override of
I1/D1/L2 configuration
- added log2(), which is generally useful
vg_main.c, valgrind.in, cachegrind.in:
- added handling of the new --{I1,D1,L2}=<size>,<assoc>,<line_size>
options
vg_cachesim.c:
- lots of stuff for auto-detecting cache configuration with CPUID.
Only handles Intel and AMD chips at the moment, and possibly not all of
them. Falls back onto defaults if anything goes wrong, and the configs
can be manually overridden from the command line anyway.
- now not printing cache summary stats if verbosity == 0. Still writing
cachegrind.out, though.
vg_cachesim_gen.c:
- new file containing stuff shared by the I1/D1/L2 simulations
vg_cachesim_{I1,D1,L2}:
- removed most of it; each now just calls a macro defined in
vg_cachesim_gen.c
vg_cachegen:
- has been cvs removed as it is no longer needed.
Makefile.am:
- added vg_cachesim_gen.c
- removed vg_cachegen
configure.in:
- removed vg_cachegen
