This function is used by GCC to enforce ordering between data writes and
instruction fetches, and while we'd prefer that users rely on the GCC
intrinsic when possible this is user visible in case that's not
possible.

[BZ #13743]
A new class of installed headers has been documented for low-level
platform-specific functionality. PowerPC added the first instance with a
function to provide time base register access (__ppc_get_timebase). This
is required for applications that measure time at high frequencies with
high precision that can't afford a syscall.
