3c128f3892 [AST] NFC: Minor performance tuning 
1) Make AnyFunctionType::getParams() inline friendly (it compiles down
   to just a few instructions).
2) Byte align/size the embedded number of AnyFunctionType parameters.
   This was set to 10 bits back when the inline bitfields were 32 bits
   in size. Now with 64 bits to play with, we have room to spare.

0c6e0c25a1 Two NFC changes: 
- Add a DominanceInfo::dominates helper functions that takes two instructions,
  as analogues to the properlyDominates ones.
- Further generalize some SILBuilder code to be more defensive in the face
  of incorrect or partially constructed SIL instructions.

These are cleanups, NFC.

f26d794495 [Conformance checking] Allow same-type constraints to infer associated types. 
When a protocol closes off an associated type by tying it to a concrete
type (e.g., via a same-type constraint), allow associated type inference
to use that information to infer the associated type rather than
requiring the user to restate the obvious.

Fixes SR-6640.

88232d6e3b [Exclusivity] Look through block arguments to find noescape closures (#13497) 
Update static enforcement to look through noescape blocks to find an underlying
noescape closure when a closure is converted to a block and passed as an
argument to a function. This fixes a false negative when the closure performs
an access that conflicts with an already in-progress access.

These new diagnostics are warnings for source compatibility but will
be upgraded to errors in the future.

82a8833ab0 [Associated type inference] Use defaults from overridden associated types. 
During associated type inference, also look for default associated type
witnesses from overridden associated types, so that one need not
redeclare default associated types at every level in a protocol hierarchy.

e0d167f1dd libSyntax: create syntax nodes for variable declarations. 
Variable declarations are declarations led by either 'var' or 'let'. It
can contain multiple pattern bindings as children.

For patterns, this patch only creates syntax nodes for simple identifier
patterns, e.g. 'a = 3'. The rest of the pattern kinds are still left
unknown (UnknownPattern).

af8d9b8c78 [silcodemotion] Instead of storing enum values directly into the block state structures, use a global "blotable" store to allow for invalidation without touching potentially free-ed pointers. Fix up all of the places where we violate this invariant.

77441fcdd1 [silcodemotion] For now stash a pointer to EnumCaseDataflowContext in each of the block states that we are tracking. 
In a subsequent commit, I will change this to use a trailing objects
implementation so we can just use pointer arithmetic to find the offset. But for
now I am going for simplicity since this is a bug fix.
