5c8e9bc070 split SILGenFunction & SGFContext out to a new header, to trim down SILGen.h 
to being global stuff.

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.

08171453da Make it a bit easier to propogate expressions around instead 
of having to lower to an RValue.

This is valuable because we can often emit an expression to a
desired abstraction level more efficiently than just emitting
it to minimal abstraction and then generalizing.

298577676e Introduce the monadic ? operator. 
A ? operator is interpreted as this if it's left-bound,
so ternary operators now have to be spaced on the left.

a1867380d0 Distinguish the "cleanup handle" and "scope" use-cases 
of CleanupsDepth.

Only with different typedefs for now, but the communicative
effect is significant.

22a3574654 Use copy_value and destroy_value when destroying loadable 
aggregates in SIL-gen.  Leave the old expanded paths around
as emitLoweredCopyValue and emitLoweredDestroyValue.

7c3e1e1dd1 SILGen: Emit semantic-to-storage conversions in implicit struct ctors. 
If a struct has [unowned] fields and an implicit elementwise constructor, then the constructor receives a strong reference argument corresponding to the unowned field, and we have to introduce that conversion as part of the construction.

115a15830b [SIL] Replace empty locations with valid locations in tuple exploding/encoding and pattern gen code. 
Tuple exploding happens during RValue construction, so changed the constructor and addElement() method to take the location parameter. The imploding happens on RValue::forwardAsSingleValue and RValue::getAsSingleValue(). Make sure the right SIL locations are passed to all of these

Also, added some missing locations in pattern matching code.
