This way we don't need to deal with the inaccuracy of decimal float literals. While we're here, modify the in-memory representation of IntegerLiteralInst and FloatLiteralInst to save the word array of the APInt instead of round-tripping through plain text.

"SILConstant" doesn't really describe its role in SIL anymore, which is to provide a reference to a Swift declaration in a SIL instruction, such as a method or nominal type field.

The new demangler is in the "swift/SIL/Demangle.{h|cpp}" files, and in the swift::Demangle namespace, which has two public entry points:
std::string demangleSymbol(llvm::StringRef mangled);
std::string demangleType(llvm::StringRef mangled);
This was necessary to support the need for LLDB to demangle Swift symbol (and type) names
Test case is included

Neither order is particularly great yet, but getting them in sync will help us keep SIL.rst coverage up as we add/remove instructions in the future.

Add a convenience SILModule::getTypeLoweringInfo forwarder, and move the emitRetainRValue and emitReleaseRValue helpers from SILGenFunction to SILBuilder so they're more readily available to non-SILGen passes. Add an emitDestroyAddress helper that emits nothing, destroy_addr, or load + release based on the value semantics of the referenced type.
Swift SVN r6431
SIL passes need to have the value semantics information in TypeLoweringInfo available by SILType. Refactor getTypeLoweringInfo into separate "derive the SILType from a Swift type" and "determine the value semantics for a SILType" stages, and index the resulting TypeLoweringInfo by both (CanType, uncurryLevel) and SILType.

As per Chris's suggestion (review of r6152), further refactored SILLocation not to derive from PointerUnion3 but to include it as a member.
In addition, added some template magic to make sure we don't have to chain dyn_casts, which I suspect will be/is happening a lot with SILLocation:
Ex:
- if (auto E = Func.dyn_cast<Expr*>()) {
- if (const FuncExpr *FE = dyn_cast<FuncExpr>(E))
- return SILLocation(FE->getBody())
+ if (const FuncExpr *FE = Func.getAs<FuncExpr>())
+ return SILLocation(FE->getBody());

In the resilience model for default arguments, the presence of a
default argument is API, but its specific value is not. Thus, the
actual default argument values can evolve over time. To implement
this, for each default argument, we emit a function that
takes no arguments and produces the default value for that
argument. The caller will then call that function to form the default
argument.
This commit emits these functions for each default argument, even
though they are not currently being called. This is part of
<rdar://problem/11561185>.
We'll probably want a different calling convention for these functions
that preserves all registers, since they will often end up being very
trivial functions.
