Because we're using a "brute-force" combination of conversion to
NSString and forwarding, this code will continue to work when String
is replaced by NewString. It may not be fast yet, but at least it
will flesh out the experience for Cocoa programmers

Add new builtins(by generalizing, renaming, and extending the builtins used for compile time integer literal checking). These new builtins truncate integers and check for overflow/truncation errors at runtime. Use these for FixedPoint conversion constructors.
Fix a routine in stdlib's String implementation and a test that relied on bitwise behavior of the constructors (and triggered overflows).
TODO:
- Teach CCP about these to get static checking.
- Add special builtins for same size signed <-> unsigned conversions.

Protocols with associated types can't currently be used as existential
types. Combined with the inability to create type constraints on
generic functions nested in generic types based on the outer type and
the inability to create closures of generic type and the inability to
create protocol constraints that require generic functions and the
inability to create protocols with init() requirements... and this is
what we get.

This creates a regression in REPL printing for class instances, which now will print the mangled class name of the instance, since Object.className was using the Swift demangler to demangle the type name. REPL printing is getting an overhaul so I think this is OK for now.

Allows us to use a copy-on-write strategy to efficiently grow Strings.
This should obviate the need for a StringBuffer class anytime soon and
make comfortable formatting efficient.
If we backslide and the COW/capacity functionality of String is no
longer doing its job, the test added here will appear to hang and
hopefully someone will be annoyed enough to fix it. We can't do
better right now because performance measurements vary based on the
test platform.

This adds builtin types Builtin.VecNxT, where N is a natural number
and T is a builtin type, which map down to the LLVM type <N x T>.
Update varous builtins to support vector arguments, e.g., binary
operations, comparisons, negation. Add InsertElement and
ExtractElement builtins for vectors.
On top of these builtins, add Vec4f and Vec4b structs to the standard
library, which provide 4xFloat and 4xBool vectors, respectively, with
basic support for arithmetic. These are mostly straw men, to be burned
down at our leisure.
Some issues as yet unresolved:
- Comparisons of Vec4f'ss are producing bogus Vec4b's, which I
haven't tracked down yet.
- We still don't support the shuffle builtin, although it should be
easy
- More testing!

Clean up the code so it better reflects the current mangling grammar. Implement demangling for concrete nominal types and some primitive types.
