Remove theoretically-unnecessary special case for icc.
Remove theoretically-unnecessary special case for icc.

Intel's icc is generally able to swallow asm blocks written for gcc.
We have a few places that don't seem to know that, though.  Experiment
with removing the special case for icc in ia64_get_bsp(); if the buildfarm
likes this, I'll try more cleanup.  This is a good test case because it
involves a "stop" notation that seems like it might not be very portable.
