Experiments show that we can safely increase our unrolling threshold without unduly impacting code size, particularly
since unrolling is not enabled at -Os.

- The COFF backend doesn't support MingW/Cygwin at the moment, it'll report an
  error, but it's still much better than random assertions from the MachO backend.
- We want to make ELF the default eventually, it's what the majority of targets use.

"The CWriter::GetValueName() method does not check if a value as an alias 
and emits the alias name which will never be defined in the output .c 
file (so the output file fails to compile). This can happen if you have 
multiple inheritance with several destructors defined by clang (...D0Ev, 
...D1Ev, ...D2Ev)."

eliminate several const_casts.

Make CallSite implicitly convertible to ImmutableCallSite.

Rename the getModRefBehavior for intrinsic IDs to
getIntrinsicModRefBehavior to avoid overload ambiguity with CallSite,
which happens to be implicitly convertible to bool.

Add support for using the FPSCR in conjunction with the vcvtr instruction, for controlling fp to int rounding.
Add support for the FLT_ROUNDS_ node now that the FPSCR is exposed.

After updating your working copy, the first build will fail because it
is using the old library dependencies. Start the build again and it
will work fine.

When the normalizeSpillWeights function was introduced, I forgot to remove this
normalization.

This change could affect register allocation. Hopefully for the better.

Scalars map being notified, as that's complicated at best, and
insufficient in general.

This means SCEVUnknown needs a non-trivial destructor, so introduce
a mechanism to allow ScalarEvolution to locate all the SCEVUnknowns.
