add a prototype for __builtin_fpclassify. We don't know how to
...
codegen it, so we get 'cannot compile this builtin function yet'
errors, just like we do currently for __builtin_isinf. However,
this should let us parse headers that use it without barfing,
which should help PR6083.

Remove the '-disable-scheduling' flag and replace it with the 'source' option of

the '-pre-RA-sched' flag. It actually makes more sense to do it this way. Also,
keep track of the SDNode ordering by default. Eventually, we would like to make
this ordering a way to break a "tie" in the scheduler. However, doing that now
breaks the "CodeGen/X86/abi-isel.ll" test for 32-bit Linux.

Produce a special diagnostic when users call a function with an argument of
...
incomplete type (or a pointer/reference to such).
The causes of this problem are different enough to justify a different "design"
for the diagnostic. Most notably, it doesn't give an operand index:
it's usually pretty obvious which operand is the problem, it adds a lot of
clutter to mention it, and the fix is usually in a different part of the file
anyway.
This is yet another diagnostic that should really have an analogue in the
non-overloaded case --- which should be much easier to write because of
the weaker space constraints.
