Fix a fastcc + sret bug. If fastcc and sret, callee doesn't need to pop the hidden struct ptr; Re-enable fastcc.

I shuffled the fast-isel command-line options around. This fixes
a bunch of fast-isel failures.

failures).

If this is the case, and also we want limited precision floating-point
calculations, then lower to do the limited-precision stuff.

the various fast-isel-related command-line options are only used
when -fast-isel itself is enabled.

the target-independent area, with improved comment.

Fix PR2757. Ignore liveinterval register allocation preference if the preference register is not in the right register class. This can happen due to sub-register coalescing.

It's already special-cased and treated as rematerializable within
LiveIntervals; this allows it to be handled by other passes
such as TwoAddressInstrctionPass.

Also, fix a subtle bug in SimplifyDemandedVectorElts'

This is a patch that was originally written by Eli Friedman,
with some fixes and cleanup by me.
