If the substitution terms of a concrete type symbol contain unresolved
name symbols, we have an invalid requirement that is dropped from the
minimized signature. In this case, the rewrite system used for minimization
cannot be installed as the official rewrite system for this generic
signature, because building a rewrite system from the signature will
produce a different result.
This might be the cause of the crash in rdar://114111159.
`module.map` as a module map name has been discouraged since 2014, and
Clang will soon warn on its usage. This patch renames all instances of
`module.map` in the Swift tests to `module.modulemap` in preparation
for this change to Clang.

When determining where the "latest opening instruction" is, consider not
just `OpenedArchetypeType`s but any `LocalArchetypeType` which includes
`PackArchetypeType`s.
Default initializable init properties shouldn't prevent default
init synthesis and such properties without anything to initialize
should be considered by it.
Fixes a bug were default initializer for an init accessor property
hasn't been synthesized even when the property is marked as default
initializable.

Add some documentation explaining the installed components and how the toolchain installation is structured. Add some details about the packaging components.
Sink down the null Decl printing into
`printDeclDescription` such that all callers
benefit from it.
This is an attempt at fixing at least the secondary
crash in rdar://113491294, it does not address the
underlying crash.
Specifically, we previously emitted a "compiler doesn't understand error", so we
were always emitting an error appropriately. This just gives a better error
message saying instead that the compiler did understand what happened and that
one cannot apply consume to globals or escaping captures.

Pre-macro-expansion conformances are introduced at the point where an
attached extension macro is attached to a particular nominal type, and
can imply other conformances. Once the macro is expanded, they are
expected to be replaced by the real conformance from the extension
produced by the macro. This includes any other conformances that are
implied by that conformances. Ensure that the real conformance---and
every conformances it implies---are considered "better" than the
pre-expansion conformances.
Fixes a bug where we would pick the wrong (pre-expansion)
conformances, which would then fail to get fully type-checked prior to
serialization. This could accept invalid code that then crashed the
compiler, as in rdar://112916159.
The order for writing records of the stdlib currently depends on
`StringMap` iteration (in a slightly roundabout manner). Sort these
alphabetically instead.
After

17 tests started to fail on Windows when when the SOURCE_DIR is on a
substitute drive due to the path expansion difference.
This fixes 7 of these tests.
