Adjust implementation of NamedTypeSymbol equality to treat generic type, constructed with modified its own type parameters, equal  to its definition when custom modifiers should be ignored.

Address FixAll performance regression in Update1

Ensure that we use a single CompilationWithAnalyzers instance for computing diagnostics with the LatestDiagnosticsGetter (FixAll code path and other explicit GetDiagnostics requests to the diagnostic service). This avoids us cloning the compilation and re-running analyzer compilation start actions once per each document for which we need to compute diagnostics.

Background analysis based off the solution crawler still creates a new CompilationWithAnalyzers instance per document analysis request as caching it in memory causes high VM usage.

This change addresses the FixAll performance regression in VS2015 Update1 reported in https://github.com/DotNetAnalyzers/StyleCopAnalyzers/pull/1979#issuecomment-166656002.

Fixes #7144.

Ensure that analyzer driver processes declared namespace symbols which are scoped to source assembly being analyzed, not the merged namespace symbols with declaring references across the compilation (including referenced assemblies).

Fix that unverifiable IL is generated for switch over Nullable<Int64> and Nullable<UInt64>

Fix incorrect async capture analysis in loops inside try.

The compiler tries to create a conversion of the expression on the case switch label to the type that is switched on. if the parameter is a Nullable this doesn't work and it assumed that the type is compatible with the underlying type of the Nullable expression. This is not the case if we have a Nullable<long> and an integer on the case switch.

Fixes #7087

When variable slot is marked unassigned, it should also be unassigned in containing try state, regardless if the current state has the slot already unassigned or not.
Existing code seems to assume that situation with variable being unasigned in the current state but assigned in the try state is impossible, but it is possible when try contains a loop and the loop contains await.

Fixes #7669

1. Add support for a simulated event queue to generate compilation events by computing declarations in the tree. Invoking GetDiagnostics to populate the event queue is one of the main reason for large allocations/VM in our perf tests. We can get back to using the compilation event queue when the compiler supports attaching an event queue to an existing compilation, without requiring a complete clone.

2. Move the cached compilation data (declarations, suppression state, etc.) out of a conditional weak table and strongly reference it in CompilationWithAnalyzers.

3. Reduce allocations in per-analyzer state maintenance by tracking analyzed declarations instead of pending declarations - latter can be very large for symbols with many declarations (e.g. global namespace).
