Switch ValueSymbolTable to use StringMap<Value*> instead of std::map<std::string, Value*>
...
as its main datastructure. There are many improvements yet to be made, but
this speeds up opt --std-compile-opts on 447.dealII by 7.3%.

Added an automatic cast to "std::ostream*" etc. from OStream. We then can
...
rework the hacks that had us passing OStream in. We pass in std::ostream*
instead, check for null, and then dispatch to the correct print() method.

Split SimpleConstantVal up into its components, so each Constant subclass gets
...
a different enum value. This allows 'classof' for these to be really simple,
not needing to call getType() anymore.
This speeds up isa/dyncast/etc for constants, and also makes them smaller.
For example, the text section of a release build of InstCombine.cpp shrinks
from 230037 bytes to 216363 bytes, a 6% reduction.
