4db2a46cff Add SIL instruction: open_existential_box_value. 
This has the same semantics as open_existential_box, but returns an object value
instead of an address.

This is used in SIL opaque values mode. Attempting to reuse open_existential_box
in this mode causes SIL type inconsistencies that are too difficult to work
around. Adding this instruction allows for consistent handling of opaque values.

The original versions of several of these currently redundant instructions will
be removed once the SIL representation stabilizes.

f657ad2d3a Rename *ExistentialOpaque instructions to *ExistentialValue. 
These instructions have the same semantics as the *ExistentialAddr instructions
but operate directly on the existential value, not its address.

This is in preparation for adding ExistentialBoxValue instructions.
The previous name would cause impossible confusion with "opaque existentials"
and "opaque existential boxes".

c1bcb0b69d SIL: add new instruction set_deallocating 
It will be used by the ReleaseDevirtualizer before calling the deallocator.
So far, this is NFC.

1e88689bad vim-utils: highlight the sil call instructions in a bolder color.

5fddd4a704 Remove the autorelease_return and strong_retain_autoreleased instructions. 
There's a buggy SIL verifier check that was previously tautological,
and it turns out that it's violated, apparently harmlessly.  Since it
was already doing nothing, I've commented it out temporarily while
I figure out the right way to fix SILGen to get the invariant right.

c7c7388cf2 Change do-while to repeat-while. 
Change all uses of "do { ... } while <cond>" to use "repeat" instead.
Rename DoWhileStmt to RepeatWhileStmt. Add diagnostic suggesting change
of 'do' to 'repeat' if a condition is found afterwards.

<rdar://problem/20336424> rename do/while loops to repeat/while & introduce "repeat <count> {}" loops

962a87f444 SIL: Rename address-only existential instructions to '{init,deinit,open}_existential_addr'. 
For better consistency with other address-only instruction variants, and to open the door to new exciting existential representations (such as a refcounted boxed representation for ErrorType).

c8d180e660 Generalize the switch_int instruction into switch_value instruction, which may switch on arguments of builtin integer types or function types. The later is required for implementing a more efficient speculative devirtualizaiton implementation. Implement lowering of switch_value into LLVM code. In case of integer operands, it reuses LLVM's switch optimizations. Support for switching on function types is not yet bullet-proof and will be refined in the subsequent patches.

c504086266 Revert r21707 "Remove the SIL is_nonnull instruction. It's no longer useful." 
We want to be able to work around problems with non-failable
Objective-C initializers actually failing, which can happen when the
API audit data incorrectly marks an initializer as non-failable.
