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.

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.

(1) code left over from the days of ConstantPointerRef:
if a use of a function is a GlobalValue then that is
not considered a reason to add an edge from the external
node, even though the use may be as an initializer for
an externally visible global!  There might be some point
to this behaviour when the use is by an alias (though the
code predated aliases by some centuries), but I think
PR2782 is a better way of handling that.  (2) If function
F calls function G, and also G is a parameter to the
call, then an F->G edge is not added to the callgraph.
While this doesn't seem to matter much, adding such an
edge makes the callgraph more regular.
In addition, the new code should be faster as well as
simpler.
