Thanks to Eric for adding the autoconf check.  It would be nice if
a cmake guru could add a cmake check for posix_spawn as well.

by switching CachedFunctionInfo from a std::map to a 
ValueMap (which is implemented in terms of a DenseMap).

DenseMap has different iterator invalidation semantics
than std::map.

This should hopefully fix the dragonegg builder.

const_casts, and it reinforces the design of the Target classes being
immutable.

SelectionDAGISel::IsLegalToFold is now a static member function, because
PIC16 uses it in an unconventional way. There is more room for API
cleanup here.

And PIC16's AsmPrinter no longer uses TargetLowering.

names.

CGSCC can delete nodes in regions of the callgraph that
have already been visited.  If new CG nodes are allocated
to the same pointer, we shouldn't abort, just handle it
correctly by assigning a new number.  This should restore
stability by removing invalidated pointers that *will* be
reused from the densemap in the iterator.

only be bitconverted to f64, ignoring the various vector types.

to determine where to place PHIs by iteratively comparing reaching definitions
at each block.  That was just plain wrong.  This version now computes the
dominator tree within the subset of the CFG where PHIs may need to be placed,
and then places the PHIs in the iterated dominance frontier of each definition.
The rest of the patch is mostly the same, with a few more performance
improvements added in.
