This makes it possible to look up the execution count corresponding to
an ASTNode through SILGenFunction. The profile reader itself is stored
in a SILGenModule: this doesn't seem like the best place for it, so
suggestions for improvement are welcome!
Next, we'll actually attach this data to SIL objects and pass it all
down to IRGen.
Adjust the definition of some diagnostics that are already called with
DeclBaseNames so that the implicit conversion from DeclBaseName to
Identifier is no longer needed.
Adjust the call side of diagnostics which don't have to deal with
special names to pass an Identifier to the diagnostic.
Diagnostic categories are entirely unused and arguably useless as
implemented, as they merely denote the sub-component of the
compiler.
As far as categorizing warnings are concerned, I'm abandoning the
effort for now, as the utility is marginal and Swift and the Swift
compiler are probalby not ready for these to be nailed down. For the
sake of cleanliness, the CATEGORY field is also stripped from
WARNINGS.
If there's a need for automatic identifying of compiler sub-components
for diagnstics in the future, there are better ways to do this.

1. Array type parsing for postfix array types Int[]. We now handle this
in the parser, but remove the AST representation of this old form. We
also stop making vague promises about the future by saying that "fixed
size arrays aren't supported... yet". Removal of this fixes a compiler
crasher too.
2. Remove the special case support for migrating @autoclosure from types
to parameters, which was Swift 1.0/1.1 syntax. The world has moved or
we don't care anymore.
3. Remove upgrade support for # arguments (nee "backtick" arguments), which
was a Swift 1.x'ism abolished in an effort to simplify method naming
rules.
NFC on valid code.
We should also eliminate the isOldSyntax as well, and just do the
error recovery in the parser (there is no need to retain the sugar here
anymore), but I'll do that as a separate change since it could be behavior
changing.
a 'var' modifier on the parameter, e.g.:
x.swift:44:5: error: cannot assign to 'let' value 'a'
a = 1
~ ^
x.swift:43:8: note: change 'let' parameter to 'var' to make it mutable
func f(let a : Int) {
^~~
var
x.swift:48:5: error: cannot assign to 'let' value 'b'
b = 2
~ ^
x.swift:47:8: note: mark parameter with 'var' to make it mutable
func g(b : Int) {
^
var
Also fix a bug where we'd incorrectly suggesting adding 'mutating' to a class
method when assigning to self in some cases.

- <rdar://problem/16306600> QoI: passing a 'let' value as an inout results in an unfriendly diagnostic
- <rdar://problem/16927246> provide a fixit to change "let" to "var" if needing to mutate a variable
We now refer to an inout argument as such, e.g.:
t.swift:7:9: error: cannot pass 'let' value 'a' as inout argument
swap(&a, &b)
^
we also produce a note with a fixit to rewrite let->var in trivial cases where mutation is
being assed for, e.g.:
t.swift:3:3: note: change 'let' to 'var' to make it mutable
let a = 42
^~~
var
The note is produced by both Sema and DI.

The previous commit enabled this; now it's just about removing the
restriction in the parser and tightening up code completion.
Using 'super' in a closure where 'self' is captured weak or unowned still
doesn't work; the reference to 'self' within the closure is treated as
strong regardless of how it's declared. Fixing this requires a cascade of
effort, so instead I just cloned rdar://problem/19755221.

- Allow 'static' in protocol property and func requirements, but not 'class'.
- Allow 'static' methods in classes - they are 'class final'.
- Only allow 'class' methods in classes (or extensions of classes)
- Remove now unneeded diagnostics related to finding 'static' in previously banned places.
- Update relevant diagnostics to make the new rules clear.

eliminating the @'s from them when used on func's. This is progress towards
<rdar://problem/17527000> change operator declarations from "operator prefix" to "prefix operator" & make operator a keyword
This also consolidates rejection of custom operator definitions into one
place and makes it consistent, and adds postfix "?" to the list of rejected
operators.
This also changes the demangler to demangle weak/inout/postfix and related things
without the @.

Lower types for SILDeclRefs from the interface types of their referents, dragging the old type along for the ride so we can still offer the context to clients that haven't been weaned off of it. Make SILFunctionType's interface types and generic signature independent arguments of its Derive the context types of SILFunctionType from the interface types, instead of the other way around. Do a bunch of annoying inseparable work in the AST and IRGen to accommodate the switchover.

Thanks to the way we've set up our diagnostics engine, there's not actually
a reason for /everything/ to get rebuilt when /one/ diagnostic changes.
I've split them up into five categories for now: Parse, Sema, SIL, IRGen,
and Frontend, plus a set of "Common" diagnostics that are used in multiple
areas of the compiler. We can massage this later.
No functionality change, but should speed up compile times!
