This fixes a crash when referencing partially-applied methods
from @_inlineable functions.
Also, curry thunks for private methods do not need shared
linkage; private is sufficient.
Textual SIL was sometimes ambiguous when SILDeclRefs were used, because the textual representation of SILDeclRefs was the same for functions that have the same name, but different signatures.

Previously, we were only able to detect factory initializers
dispatched through class_method. This didn't work for
factory initializers defined in protocol extensions.
The end result would be that we would strong_release an
uninitialized class instance, which could cause crashes.
Fix DI to correctly release the old instance using
dealloc_partial_ref instead.
Fixes <rdar://problem/27713221>.
Add yet one more flavor of hack to DI to recognize where we are
delegating the initialization of 'self'. The existing hack in this
area (for Objective-C factory initializers) is based on recognizing
the value_metatype instruction that feeds into the application of the
factory initializer. C functions imported as initializers don't have a
metatype argument, so instead tag the assignment into the self box as
the initialization of self.
As a minor cleanup in this area, don't emit the dead value_metatype
instruction when invoking a C-imported factory initializer.
Having a separate address and container value returned from alloc_stack is not really needed in SIL.
Even if they differ we have both addresses available during IRGen, because a dealloc_stack is always dominated by the corresponding alloc_stack in the same function.
Although this commit quite large, most changes are trivial. The largest non-trivial change is in IRGenSIL.
This commit is a NFC regarding the generated code. Even the generated SIL is the same (except removed #0, #1 and @local_storage).
