reportable bugs.
AIX only: print name of missing syscall as well as number -- important
because there is no fixed name/number binding.

VG_(record_startup_wd) which records the working directory at startup,
and VG_(get_startup_wd) which later tells you what value was recorded.
This works because all uses of VG_(getcwd) serve only to record the
directory at process start anyway. The motivation is that AIX does
not support sys_getcwd directly, so it's easier for the launcher to
ship in the required value using an environment variable. On Linux
sys_getcwd is used as before.

This hopefully makes the whole issue with cycles easier to understand.
And no, this does not get rid of the description of cycles, carefully
crafted by Julian ;-)

* Looks a little bit more like the Cachegrind manual
(at least in front)
* Removed the out-of-place general section about profiling
and gprof. Perhaps something like this can be put at
another place
* Notes about Callgrinds problems with call tracing on PPC
* Include usage of callgrind_annotate, and note its lack of
cycle detection

--branch-sim=yes is specified, Cachegrind simulates a simple indirect
branch predictor and a conditional branch predictor. The latter
considers both the branch instruction's address and the behaviour of
the last few conditional branches. Return stack prediction is not
modelled.
The new counted events are: conditional branches (Bc), mispredicted
conditional branches (Bcm), indirect branches (Bi) and mispredicted
indirect branches (Bim). Postprocessing tools (cg_annotate, cg_merge)
handle the new events as you would expect. Note that branch
simulation is not enabled by default as it gives a 20%-25% slowdown,
so you need to ask for it explicitly using --branch-sim=yes.

and hence to segfaulting in vex on ppc32/64-linux in obscure
circumstances. VKI_MAX_PAGE_SIZE is 64k in recent Valgrinds.

- extend some to 2007
- use njn@valgrind.org instead of njn25@cam.ac.uk
- use "tool" instead of "skin"

some attempt to discard existing translations first. Otherwise
Cachegrind (rightly) asserts on the basis that it is seeing duplicate
translation requests for the same entry point.

Had to change XArray's comparison function to return an Int rather than a
Word so it's consistent with the rest of the world.
