Account for scalarization costs in BasicTTI::getMemoryOpCost for extending vector loads
When a vector type legalizes to a larger vector type, and the target does not
support the associated extending load (or truncating store), then legalization
will scalarize the load (or store) resulting in an associated scalarization
cost. BasicTTI::getMemoryOpCost needs to account for this.

Fix multi-register costs in BasicTTI::getCastInstrCost
For an cast (extension, etc.), the currently logic predicts a low cost if the
associated operation (keyed on the destination type) is legal (or promoted).
This is not true when the number of values required to legalize the type is
changing. For example, <8 x i16> being sign extended by <8 x i32> is not
generically cheap on PPC with VSX, even though sign extension to v4i32 is
legal, because two output v4i32 values are required compared to the single

Simplify communication between Resolver and Input Graph.
Resolver is sending too much information to Input Graph than Input
Graph actually needs. In order to collect the detailed information,
which wouldn't be consumed by anyone, we have a good amount of code
in Resolver, Input Graph and Input Elements. This patch is to
simplify it. No functionality change.
Specifically, this patch replaces ResolverState enum with a boolean
value. The enum defines many bits to notify the progress about
linking to Input Graph using bit masks, however, what Input Graph
actually does is to compare a given value with 0. The details of
the bit mask is simply being ignored, so the efforts to collect
such data is wasted.
This patch also changes the name of the notification interface from
setResolverState to notifyProgress, to make it sounds more like
message passing style. It's not a setter but something to notify of
an update, so the new name should be more appropriate than before.

ARM64: use GOT for weak symbols & PIC.
Weak symbols cannot use the small code model's usual ADRP sequences since the
instruction simply may not be able to encode a value of 0.
This redirects them to use the GOT, which hopefully linkers are able to cope
with even in the static relocation model.

SLPVectorizer: compare entire intrinsic for SLP compatibility.
Some Intrinsics are overloaded to the extent that return type equality (all
that's been checked up to now) does not guarantee that the arguments are the
same. In these cases SLP vectorizer should not recurse into the operands, which
can be achieved by comparing them as "Function *" rather than simply the ID.

Summary:
Add support for named values in the parser.
This allows injection of arbitrary constants using a custom Sema object.
Completions are not supported right now.
Will be used by clang_query to support the 'let' command.
Usage example:

clang_query> match varDecl(hasType(unique_ptr))

Replace INVALID/INVALID_NOVERIFY with diagnostics.
This replaces the ancient INVALID/INVALID_NOVERIFY macros with a real
function.
The new invalid(..) function uses small diagnostic objects that are
generated on demand. We can store arbitrary additional information per
error type and generate useful debug/error messages on the fly.
Use it as follows:
if (/* Some error condition (ReportFoo) */)
invalid<ReportFoo>(Context, /*Assert=*/true/false,
(/* List of helpful diagnostic objects */));
Where ReportFoo is a subclass of RejectReason that is able to take the
list of helpful diagnostic objects in its constructor.
The implementation of invalid will create the report and fire
an assertion, if necessary.
