ADD AT_DCACHEBSIZE and AT_HWCAP2 support for POWER PC 

Valgrind currently does not support the following AUX vector entries:
AT_DCACHEBSIZE, and AT_HWCAP2. By default these entries are suppressed by
Valgrind. The attached patch adds the needed support so the user level programs
can correctly determine that hardware level they are running on. Specifically
that the ISA 2.07 for Power 8 is supported.

Bugzilla 345695

This fix adds the needed support.  It makes a minor change to allow the
VEX settings of the host platform to be passed down so they can be checked
against the HWCAP values.
