As soon as you had one &&/|| in your chain of expressions we would lose
infix completions for Bool because we got confused by the autoclosure,
so strip it off.

Constructor call patterns already get a real priority, but because of
the way we do function call patterns we don't have enough information,
and previously we were setting it to "expression specific", which is
unnecessarily high, particularly since functions (unlike inits) have
other better ways to code-complete already.

When completing
Foo(<here>
We will now provide
bar: <#value#>
instead of
bar: <#value#>)
Inserting the rparen caused some problems in practice:
* the old behaviour optimized for typing Foo(<complete> instead of
Foo(<complete>), which can conflict with user behaviours or ...
* in editors with automatic brace-matching, we often conflicted with the
editor, leading to extraneous closing parens
And in general, it is much more predictable for tooling to either insert
matching ( and ) or to not insert either. While this change may not be
ideal For users of editors that do not do automatic brace-matching, I
believe it is still better overall to have to type a missing paren than
to have to delete an extraneous one.

The original hope was we could make these heuristics really good, but
since that is not currently in sight (and may never be), we want to be
able to turn them off. For now, just plumb through an internal flag to
control the behaviour. A future change will customize the behaviour in
SourceKit.

Some of the implicit decls generated for lazy vars have invalid source ranges.
For now, just always walk into implicit decls when looking for name locations.
Resolves rdar://problem/35255644.
- Outlaw duplicate input files, fix driver, fix tests, and add test.
- Reflect that no buffer is present without a (possibly pseudo) named file.
- Reflect fact that every input has a (possible pseudo) name.
- Break up CompilerInstance::setup.
Don't bail on dups.
Adds support for renaming subscripts with external names, e.g.
subscript(x y: Int), and introduces a noncollapsible parameter name range for
subscript parameters, since these shouldn't be collapsed with an argument label
of the same name as function parameter names are.
NameMatcher checked if a StringLiteralExpr was a string segment in an
interpolated string by checking if the parent expression was an
InterpolatedStringLiteralExpr. That's only true pre-type-checking, and unlike
global rename, local rename uses the type-checked AST.
Rather than storing contextual types in the type witnesses and associated
conformances of NormalProtocolConformance, store only interface types.
@huonw did most of the work here, and @DougGregor patched things up to
complete the change.
Support for @noescape SILFunctionTypes.
These are the underlying SIL changes necessary to implement the new
closure capture ABI.
Note: This includes a change to function name mangling that
primarily affects reabstraction thunks.
The new ABI will allow stack allocation of non-escaping closures as a
simple optimization.
The new ABI, and the stack allocation optimization, also require
closure context to be @guaranteed. That will be implemented as the
next step.
Many SIL passes pattern match partial_apply sequences. These all
needed to be fixed to handle the convert_function that SILGen now
emits. The conversion is now needed whenever a function declaration,
which has an escaping type, is passed into a @NoEscape argument.
In addition to supporting new SIL patterns, some optimizations like
inlining and SIL combine are now stronger which could perturb some
benchmark results.
These underlying SIL changes should be merged now to avoid conflicting
with other work. Minor benchmark discrepancies can be investigated as part of
the stack-allocation work.
* Add a noescape attribute to SILFunctionType.
And set this attribute correctly when lowering formal function types to SILFunctionTypes based on @escaping.
This will allow stack allocation of closures, and unblock a related ABI change.
* Flip the polarity on @noescape on SILFunctionType and clarify that
we don't default it.
* Emit withoutActuallyEscaping using a convert_function instruction.
It might be better to use a specialized instruction here, but I'll leave that up to Andy.
Andy: And I'll leave that to Arnold who is implementing SIL support for guaranteed ownership of thick function types.
* Fix SILGen and SIL Parsing.
* Fix the LoadableByAddress pass.
* Fix ClosureSpecializer.
* Fix performance inliner constant propagation.
* Fix the PartialApplyCombiner.
* Adjust SILFunctionType for thunks.
* Add mangling for @noescape/@escaping.
* Fix test cases for @noescape attribute, mangling, convert_function, etc.
* Fix exclusivity test cases.
* Fix AccessEnforcement.
* Fix SILCombine of convert_function -> apply.
* Fix ObjC bridging thunks.
* Various MandatoryInlining fixes.
* Fix SILCombine optimizeApplyOfConvertFunction.
* Fix more test cases after merging (again).
* Fix ClosureSpecializer. Hande convert_function cloning.
Be conservative when combining convert_function. Most of our code doesn't know
how to deal with function type mismatches yet.
* Fix MandatoryInlining.
Be conservative with function conversion. The inliner does not yet know how to
cast arguments or convert between throwing forms.
* Fix PartialApplyCombiner.
Except GenericEnvironment.h, because you can't meaningfully use a
GenericEnvironment without its signature. Lots less depends on
GenericSignature.h now. NFC
Encapsulate uses of the variables in FrontendInputs with intention-describing functions. Move some code that sets these variables into FrontendInputs and FrontendOptions classes.
Create new FrontendInputs class to encapsulate InputFilenames, InputBuffers and PrimaryInput, which were formerly in Frontend.
Includes one change in SwiftEditor.cpp to resolve a merge conflict.
... and UnicodeScalar, which is technically more correct than only
showing it for String. This also happens to workaround a bug where we
won't show "" for string.contains.

* [IDE] Refactoring: conversion from “force try” do error handled version
* Removed unnecessary empty line
* Changed name of the refactor
* Review fixes
* Fixed recognizing try_! location by CursorResolver
* Review fixes
In one place we were calling hasError() and in another directly checking
for ErrorType; if we had a type containing an ErrorType as a structural
component, we would hit an assertion.
We have a hack where we use the ParsedDecl as the DeclContext,
to handle completion during function signature parsing, which
happens before the FuncDecl has been created.
While fixing this properly would require a bigger change to the
parser and AST, for now we just check if the ParsedDecl is a
child context of CurDeclContext, and only use it then.
