607114f6c6 Introduce a new "emitDestroyAddr" function, which attempts to fold destroy_addr into 
preceding copy_addr instruction when totally trivial.  Adopt this in SILGen, eliminating
a couple dozen destroy_addr instructions from the stdlib and producing more canonical SIL.

3f5c0dbf0e Update SILArgument::getModule(), SILBasicBlock::getModule() and SILInstruction::getModule() signatures to match SILFunction::getModule(), for consistency; standardize usage of SILFunction::getParent() to SILFunction::getModule().

04b4901b79 [SIL] Split emitBlock() into 2 to remove dependency on construction of a NULL SILLocation.

1ba2554fb2 [SIL] Ensure that all loop branches have valid locations. 
Also, change the location of "looping back to head" branch to point to the closing brace of the body, which is a more natural source location than the beginning of the enclosing loop statement.

4d7de376bb [SIL] Refactor splitBasicBlock() into splitBasicBlock and splitBasicBlockAndBranch 
This API is more explicit and avoids relying on passing around empty SILLocation.
(No functional change.)

a864b8ea00 enhance the union retain/release implementations to split the block when 
inserting a diamond into the middle of an existing block.  This fixes a
problem that manifests in memory promotion when lowering an assign.

d7b6009374 Introduce the concept of the "semantic" type of a lowered 
type and audit a great deal of code to deal with it appropriately.

Spot fixes in a few other places.

8ac1bda817 SIL: Move retain/release/destroy helpers onto SILBuilder. 
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.
