wherever it appears to match the current kernel source.
Also fixup the PRE handler to do the check correctly, using the
size field of the structure to work out how much data there is.

swapping the roles of the VALGRIND_DO_CLIENT_REQUEST() and
VALGRIND_DO_CLIENT_REQUEST_EXPR() macros. Also, many __attribute__((unused))
declarations on variables have been eliminated. Closes#269778.
Note: so far this patch has been tested on x86/Linux, amd64/Linux and
ppc64/Linux but not yet on any other supported CPU/OS combination.

identical to VG_(newXA) but allows passing in a size hint. In the
case where the likely final size of the XArray is known at creation
time, this allows avoiding the repeated (implicit) resizing and
copying of the array as elements are added, which can save a vast
amount of dynamic memory allocation turnover.

by Kirill Batuzov, batuzovk@ispras.ru. This fixes the main bug in

and seeing whether it SIGILLs. Apparently the latter is not a
reliable way to ascertain the presence of usable Neon support. Fixes
