1df3d1a33c Frontend: Don't interleave parsing and typechecking for the main file
SIL files still require this behavior; if we cleaned that up we
could simplify a fair bit of code here.

8fae0893e1 [CodeCompletion] Don't use temporary Lexer in the second pass
Since we only call one parsing function (i.e. parseAbstructFunctionBody,
parseDecl, or parseStmtOrExpr), the parser stops at the end of the node.
It's not necessary to limit the Lexer to set an ArtificialEOF.

To minimize the parsing range, modify the Parser to *not* parse the body
if the completion happens in the signature.

0267384e11 Fixup SourceKit and Tests
Patch up all the places that are making a syntactic judgement about the
isInvalid() bit in a ValueDecl.  They may continue to use that query,
but most guard themselves on whether the interface type has been set.

742f6b2102 Drastically Simplify VarDecl Validation
This is an amalgam of simplifications to the way VarDecls are checked
and assigned interface types.

First, remove TypeCheckPattern's ability to assign the interface and
contextual types for a given var decl.  Instead, replace it with the
notion of a "naming pattern".  This is the pattern that semantically
binds a given VarDecl into scope, and whose type will be used to compute
the interface type. Note that not all VarDecls have a naming pattern
because they may not be canonical.

Second, remove VarDecl's separate contextual type member, and force the
contextual type to be computed the way it always was: by mapping the
interface type into the parent decl context.

Third, introduce a catch-all diagnostic to properly handle the change in
the way that circularity checking occurs.  This is also motivated by
TypeCheckPattern not being principled about which parts of the AST it
chooses to invalidate, especially the parent pattern and naming patterns
for a given VarDecl.  Once VarDecls are invalidated along with their
parent patterns, a large amount of this diagnostic churn can disappear.
Unfortunately, if this isn't here, we will fail to catch a number of
obviously circular cases and fail to emit a diagnostic.

77924c4b84 [Parser] Decouple the parser from AST creation (part 2)
Instead of creating the AST directly in the parser (and libSyntax or
SwiftSyntax via SyntaxParsingContext), make Parser to explicitly create
a tree of ParsedSyntaxNodes. Their OpaqueSyntaxNodes can be either
libSyntax or SwiftSyntax. If AST is needed, it can be generated from the
libSyntax tree.

1535bea268 FixCode: issue a separate note for protocol-stub fixit when the fixit location is in another file
Under non-editor mode, the fixit for inserting protocol stubs is associated with a note
pointing to the missing protocol member declaration which could stay in a separate file from
the conforming type, leading to the behavior of rdar://51534405. This change checks if
the fixit is in a separate file and issues another note to carry the fixit if so.

95eea2f3e9 [Parse] Implement "missing 'func' keyword" diagnostic with a fix-it
- When parsing a type or extension declaration, attempt to parse a function or property declaration when meeting an identifier, an operator or a paren (for tuple declarations).
- Produce the diagnostic with a fix-it suggesting to insert the needed keyword
- Recover parsing as if the declaration with the missing keyword is a function/property declaration

3fda509805 Implementation of ElementaryFunctions / Real protocols.
This commit implements SE-0246, by adding conformance to Real to the Float, CGFloat, Double, and Float80 types, implemented either in terms of the system's C math library, existing standard library functionality, or LLVM intrinsics. It includes basic test coverage for these new functions, and deprecates and obsoletes *some* existing functionality in the Platform overlay. We still need to make a decision about how to handle the remaining "tgmath" functions, because obsoleting them is technically a source-breaking change (if users have unqualified names like "exp(1)", it's fine, but it would break users who have used qualified names like "Darwin.exp(1)".)

8ee52763f0 Remove the '++' and '--' operators.
We still had unavailable versions of these for floating-point types
only. We shouldn't need to keep these around, and can instead just
emit a helpful diagnostic for anyone that attempts to use them.

Unfortunately I don't see any way for the diagnostic to produce an
actual fix-it, so it just suggests '+= 1' or '-= 1' without actually
producing a fix.

1d6f11ab54 Refactor ArrayExpr visitor for better QoI
Also remove mention of the word “contextual” type from the diagnostic
that rewrites array literals into dictionary literals and scale back
the scope of the diagnostic.  This method was catching and
mis-diagnosing too many errors that could better be handled by invalid
conversion diagnostics.
