We want to use the reserved space in the metadata pattern for protocol conformance caching, and this link lets us find the metadata pattern from an instance of the generic type.

This reverts commit r22829, because reverting r22828 depends on it.
Reverting r22828 because it
was apparently causing an assertion on the bot:

terminators"
This is an assumption that the SSAUpdater makes. Verify that we preserve this
property.
With changes to the test cases, SIL documentation and add a critical edge (non
cond_br only) splitting pass to the mandatory pipeline.
This reapplies commit 22775.

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.

Specifically:
I Moved ref_to_unowned and unowned_to_ref to conversion inst section so
we match SILNodes.def.
I added full docs for:
1. unchecked_trivial_bit_cast
2. unchecked_ref_bit_cast
and stub docs for:
1. objc_protocol.
2. autorelease_value.
3. init_block_storage_header
4. project_block_header

We currently mangle private declarations exactly like public declarations,
which means that private entities with the same name and same type will
have the same symbol even if defined in separate files.
This commit introduces a new mangling production, private-decl-name, which
includes a discriminator string to identify the file a decl came from.
Actually producing a unique string has not yet been implemented, nor
serialization, nor lookup using such a discriminator.
Part of rdar://problem/17632175.

instances of Swift subclasses of ObjC classes.
We were already doing this in the runtime. This patch
unhides the runtime's mask word (swift_isaMask) and makes
IR-gen take advantage of it when it can.

initializeBufferWithTakeOfBuffer value witness.
Attempt to use initializeBufferWithTakeOfBuffer in
some appropriate places.
There are some changes enabled by this which are
coming in a follow-up patch.

Squash _[Conditionally]BridgedToObjectiveC into one protocol. This
change results in simpler bridging code with fewer dynamic protocol
conformance checks, and solves the nasty naming/semantics problem that
resulted from having _ConditionallyBridgedToObjectiveC refining
_BridgedToObjectiveC.
Also, rename things so they're more symmetrical and less confusing.
