Sema: Record the trail step count in solver statistics
...
Also introduce two new frontend flags:
The -solver-scope-threshold flag sets the maximum number of scopes, which was
previously hardcoded to 1 million.
The -solver-trail-threshold flag sets the maximum number of trail steps,
which defaults to 64 million.

Sema: Fix handling of appliedPropertyWrappers in ConstraintSystem::replaySolution()
...
When we replay a solution, we must record changes in the trail, so fix the
logic to do that. This fixes the first assertion failure with this test case.
The test case also exposed a second issue. We synthesize a CustomAttr in
applySolutionToClosurePropertyWrappers() with a type returned by simplifyType().
Eventually, CustomAttrNominalRequest::evaluate() looks at this type, and passes
it to directReferencesForType(). Unfortunately, this entry point does not
understand type aliases whose underlying type is a type parameter.
However, directReferencesForType() is the wrong thing to use here, and we
can just call getAnyNominal() instead.
Fixes rdar://139237781.

[CSSolver] DynamicMemberLookup: Ignore disabled choices while filtering disjunctions
...
`filterDisjunction` should ignore the choices that are already
disabled while attempting to optimize disjunctions related to
dynamic member lookup.

[Constraint solver] Disable fallback diagnostic when error emitted into a transaction
...
When we are using diagnostic transactions to disable immediate emission
of diagnostics, `DiagnosticEngine::hadAnyError()` no longer accurately
reports whether an error occurred. Thread the DiagnosticTransaction
into the ConstraintSystem so we can also check whether it contains an
error before emitting the fallback diagnostic.
Fixes rdar://128272346.
