Add a new version of Module::getFunction that takes a const char* instead
...
of a std::string. This avoids copying the string to the heap in common
cases. Patch by Pratik Solanki!

Refactor SymbolTableListTraits to only have a single pointer in it, instead
...
of two. This shrinkifies Function by 8 bytes (104->96) and Module by 8
bytes (68->60). On a testcase of mine, this reduces the memory used to
read a module header from 565680b to 561024, a little over 4K.

symbol table does no allocations for prototypes or other lazily deserialized

Start value symbol tables out small (space for 16 elts), not huge (space for 512).

This is particularly useful for the JIT, which lazily deserializes functions.

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%.

This patch replaces the SymbolTable class with ValueSymbolTable which does
not support types planes. This means that all symbol names in LLVM must now
be unique. The patch addresses the necessary changes to deal with this and
removes code no longer needed as a result. This completes the bulk of the
changes for this PR. Some cleanup patches will follow.

First step in refactoring the SymbolTable is to split it into two classes,
one for a symbol table of types and one for a symbol table of Values.
