Add a 'hasExplicitAnyObject()' bit to ProtocolCompositionType
to represent canonical composition types containing '& AnyObject'.
Serialize this bit and take it into account when building
ExistentialLayouts.
Rename ProtocolCompositionType::getProtocols() to getMembers()
since it can contain classes now, and update a few usages that
need further attention with FIXMEs or asserts.
For now, nothing actually constructs these types, and they will
trigger arounds asserts. Upcoming patches will introduce support
for this.
A lot of files transitively include Expr.h, because it was
included from SILInstruction.h, SILLocation.h and SILDeclRef.h.
However in reality most of these files don't do anything
with Exprs, especially not anything in IRGen or the SILOptimizer.
Now we're down to 171 files in the frontend which depend on
Expr.h, which is still a lot but much better than before.
1. Make sure the actions taken by fixits are reflected in diagnostics messages.
2. Issue missing cases diagnostics at the start of the switch statement instead of its end.
3. Use <#code#> instead of <#Code#> in the stub.
SourceKit always sets it positively. This may lead to more aggressive fixits however
less informative messages. We currently use the flag only for filling protocol stubs.
If a documentation comment has a - LocalizationKey: field, strip it
out of the documentation body and report it in cursor/doc info with
the key "key.localization_key".

Add an option to the lexer to go back and get a list of "full"
tokens, which include their leading and trailing trivia, which
we can index into from SourceLocs in the current AST.
This starts the Syntax sublibrary, which will support structured
editing APIs. Some skeleton support and basic implementations are
in place for types and generics in the grammar. Yes, it's slightly
redundant with what we have right now. lib/AST conflates syntax
and semantics in the same place(s); this is a first step in changing
that to separate the two concepts for clarity and also to get closer
to incremental parsing and type-checking. The goal is to eventually
extract all of the syntactic information from lib/AST and change that
to be more of a semantic/symbolic model.
Stub out a Semantics manager. This ought to eventually be used as a hub
for encapsulating lazily computed semantic information for syntax nodes.
For the time being, it can serve as a temporary place for mapping from
Syntax nodes to semantically full lib/AST nodes.
This is still in a molten state - don't get too close, wear appropriate
proximity suits, etc.
This provides a stream utility for writing to a underlying string buffer multiple string pieces and retrieve them later as StringRef when the underlying buffer is stable.
This has the effect of propagating the search path to the clang importer as '-iframework'.
It doesn't affect whether a swift module is treated as system or not, this can be done as follow-up enhancement.
