772d7ec3c5 Merge branch 'SE-0067' of https://github.com/stephentyrone/swift into stephentyrone-SE-0067 
Implements almost all of SE-0067. There are a few outstanding features; this implementation does not have:

- formRemainder(dividingBy:)
- formSquareRoot()
- addProduct(_:,_:)

which require additions to the Builtin module. I can probably figure out how to do these, but I haven't had a chance to do so yet. Also missing are the generic initializers and comparisons whose implementation depends on having new Integer protocols.

The last remaining feature of SE-0067 is that while the basic operators +,-,*,/, etc are moved onto the FloatingPoint protocol, they are still required on the concrete types in order to disambiguate overloads. Fixing this seems to require either modifying the overload resolution rules or removing these operators from some other protocols. Or it might just require that someone smarter than me looks at the problem.

Passes the existing tests locally (with the included changes). I'm working on additional tests for the new features.

e75dae491e Don't diagnose failures to call symmetrically-typed binary operators 
as a failure to convert the individual operand, since the operator
is likely conceptually generic in some way and the choice of any
specific overload is probably arbitrary.

Since we now fall back to a better-informed diagnostics point, take
advantage of this to generate a specialized diagnostic when trying to
compare values of function type with ===.

Fixes rdar://25666129.

This reverts commit 073f427942,
i.e. it reapplies 35ba809fd0 with a
test fix to expect an extra note in one place.

module completely if it did not have a field metadata section.
This is of course wrong if the module defines closures but
not nominal types.

6429eabf74 Implement the new FloatingPoint protocols from SE-0067. 
There are a couple of features that are not yet implemented, because they require additions to the Builtin module.  Specifically, this implementation does not have:

- formRemainder(dividingBy:)
- formSquareRoot()
- addProduct(_:,_:)

Also missing are the generic initializers and comparisons whose implementation depends on having new Integer protocols.

The last remaining feature of SE-0067 is that while the basic operators +,-,*,/, etc are moved onto the FloatingPoint protocol, they are still required on the concrete types in order to disambiguate overloads.  Fixing this seems to require either modifying the overload resolution rules or removing these operators from some other protocols.  Or it might just require that someone smarter than me looks at the problem.

Passes all the existing tests (with the included changes).  I'm working on additional tests for the new features.

5f5ce39a1d SwiftRemoteMirror: Wire up existential projection API 
Implement the ReflectionContext's implementation of:
swift_reflection_projectExistential.

First, we get the type info of the existential typeref - it should be a
record type info. If it's a class existential, it has trivial layout:
the first word is a pointer to the class instance. Otherwise, if the
value fits in the 3-word buffer of the existential container, it
trivially is also at the start of the container. Otherwise, the value is
off in a heap box somewhere, but the first word of the container is a
pointer to that box.
