20e58dcf93 Change the type of function values in SIL to SILFunctionType. 
Perform major abstraction remappings in SILGen.  Introduce
thunking functions as necessary to map between abstraction
patterns.

19457c12ea Give Builtin.Word an abstract size. 
Instead of hardcoding Builtin.Word to be an alias for Builtin.Int64, make it its own type of abstract pointer width.

- Change BuiltinIntegerType's width representation to accommodate abstract widths.

- In the AST and in SIL, store values of the types as the greatest supported size for the abstract width (64 bits for a pointer).

- Add some type safety to the ([sz]ext|trunc)(OrBitCast)? builtins that they're used appropriately given the upper and lower bounds of the abstract sizes they're working with.

- Now that Builtin.Word is a distinct type, give it its own mangling.

- In IRGen, lower pointer-sized BuiltinIntegerType appropriately for the target, and truncate lowered SIL values if necessary.

Fixes <rdar://problem/15367913>.

e05c03d5bc Standardize terminology for "computed", "stored", "variable", and "property". 
These are the terms sent out in the proposal last week and described in
StoredAndComputedVariables.rst.

variable
  anything declared with 'var'
member variable
  a variable inside a nominal type (may be an instance variable or not)
property
  another term for "member variable"
computed variable
  a variable with a custom getter or setter
stored variable
  a variable with backing storage; any non-computed variable

These terms pre-exist in SIL and IRGen, so I only attempted to solidify
their definitions. Other than the use of "field" for "tuple element",
none of these should be exposed to users.

field
  a tuple element, or
  the underlying storage for a stored variable in a struct or class
physical
  describes an entity whose value can be accessed directly
logical
  describes an entity whose value must be accessed through some accessor
