Justin Hibbits 2914706ab0 powerpc64: Add DSCR support 
Summary:
Powerpc64 has support for a register called Data Stream Control Register
(DSCR), which basically controls how the hardware controls the caching and
prefetch for stream operations.

Since mfdscr and mtdscr are privileged instructions, we need to emulate them,
and
keep the custom DSCR configuration per thread.

The purpose of this feature is to change DSCR depending on the operation, set
to DSCR Default Prefetch Depth to deepest on string operations, as memcpy.
