For a function call used to take [String: Any]? as argument and now
takes [StringRepresentableStruct: Any]?, a helper function is inserted
to help the bridging of types.
When a user's code calls a function that used to take [String: Any] as
argument and now takes [StringRepresentableStruct: Any], this migration
inserts a helper function to convert the argument to the
expected type.
This patch migrates simple attribute assignment and reference when the
attribute used to be of type String and later became StringRepresentable struct.

* Simplify TupleTypeRepr parsing
This patch introduces a TupleTypeReprElement struct that holds the
locations for all relevant bits of tuple elements. It removes the
NameLoc and UnderscoreLoc arrays from TupleTypeReprElement in favor of
holding each of these on TupleTypeReprElement. These extra bits of info
are required for full-fidelity representation in the Syntax library.
* Remove TupleTypeReprBitfields and move EllipsisLoc out of TrailingObjects
* Update users of TupleTypeRepr
* Don't resize the elts if we're going to push_back
* getType -> getElementType
* Move ellipsis back into TrailingObjects.
* Move NumElements into TupleTypeReprBitfields
Previously, we only handle dot syntax call expression for qualified
replacement, i.e. changing from A.a to B.b. This patch teaches the tool
to handle the migration of member reference expression tool.
Post-commit review follow-up:
This works better for properties that were all-caps, such as `URL`.
Thanks @harlanhaskins for the tip!

Situations where there is a contextual RawRepresentable type is
used incorrectly would produce `<Type>(rawValue: )` fix-it only
in cases where neither or both sides of the expression are optional.
Let's fix that by adding a fix-it for optional to contextual raw
value type conversion.

This patch restricts the detection of moved members to be static members,
since only in this case we need to update qualified access to
them. The move of instance members will be either handled by rename or
we don't need to update anything at all.
Additionally, this patch introduces a sub-kind of type member diff item
called qualified replacement to describe the aforementioned case. However,
the migrator part has not started to honor this sub-kind yet.

We used to only migrate them in call sites, e.g. changing from
``p.getHeight()`` to ``p.Height``. However, with experimenting on more real-world
projects, we realize migrating overrides is equally important.

If the replacement type was a function type or protocol-constrained type (e.g. 'Class & Proto) and the existing type had a postfix ? or !, we weren't wrapping the replacement in parens. This would result in an incorrect/ambiguous new type. This patch wraps the replacement in parens if it contains an & or ->, the existing type has a trailing ? or !.

The SyntacticMigratorPass is getting Too Big To Fail and covers
multiple migrations. There was already an early exit to not run
the pass if APIDigesterDataStorePath wasn't supplied, so SE-0110
tuple splat fix-its weren't getting run. This manifested in Migrator
tests not printing migrated contents on Linux.
New: ASTMigratorPass
Renamed: SyntacticMigratorPass -> APIDiffMigratorPass
New: TupleSplatMigratorPass
These implementations are entirely hidden and can only be invoked
by a swift::migrator function.
