predicates.  For example if we have:

Scope:
  CheckType i32
    ABC
  CheckType f32
    DEF
  CheckType i32
    GHI

Then we know that we can transform this into:
Scope:
  CheckType i32
    Scope
      ABC
      GHI
  CheckType f32
    DEF

This reorders the check for the 'GHI' predicate above
the check for the 'DEF' predidate.  However it is safe to do this
in this situation because we know that a node cannot have both an
i32 and f32 type.

We're now doing more factoring that the old isel did.

means "all the way to to the emitter code, but not across 
ComplexPatterns".  This substantially increases the amount of factoring
we get.

copy the source buffers provided rather than referencing them
directly, so that the caller can free those buffers immediately after
calling clang_createTranslationUnitFromSourceFile(). Otherwise, we
risk hitting those buffers later (when building source ranges, forming
diagnostics, etc.).

This is possible because F8RC is a subclass of F4RC. We keep FMRSD around so
fextend has a pattern.
