Local functions update (generics)

Definite assignment, generic iterators, symbol display, and parser fixes

[Automated] Merge 'stabilization' and 'master' into 'future'

Restore assemblies removed from vsix

System.Composition.Convention|Hosting|TypedParts
System.Collections.Immutable
System.Reflection.Metadata

Only restored to Roslyn.VisualStudio.Setup.vsix

Don't cache ValueSource's for producing trees for DocumentStates that don't 'Support Syntax Tree'.

Change detection of double 0.0 to use BitConverter.DoubleToInt64Bits

Underneath BitConverter just casts 64bit double to a 64bit int with the same bit pattern, making it a simpler operation.

Add initial documentation on localizing analyzers.

This includes the
following:

* Setting up a project to use localized resources
 * Using localized resources in Analyzers
 * Using localized resources in Code Fixes
* Producing localized resource assemblies
* Packaging resource assemblies in NuGet packages and VSIXes
* Testing the localization at the command line and in VS

Fixes #3542.

#2033: CA1052: Incorporate PR feedback from @cston

Add initial documentation on localizing analyzers. This includes the
following:

* Setting up a project to use localized resources
 * Using localized resources in Analyzers
 * Using localized resources in Code Fixes
* Producing localized resource assemblies
* Packaging resource assemblies in NuGet packages and VSIXes
* Testing the localization at the command line and in VS

Fixes #3542.

This ends up creating an unending chain of ValueSources to lazily realize a tree for a
document that will never end up producing a tree.  This manifests as a very slow memory
leak.

Move intermediate build output to the Binaries directory

Fix signed build

Recently, a change was made to exclude assemblies that are part of Visual
Studio from all VSIXes.  However, VSIXes that are to be included obviously
need to be able to include such assemblies, so we use the new
ForceIncludeInVsix element to override the filtering.

Update Roslyn to work with the MEF Composition API changes.

#2033: Fix CA1052/1053 analyzers

Remove ReflectionEmitter

Several of our code generator tools were handling any
argument which started with a '/' as a switch.  On Linux / Mac
this can also represent a fully qualified path.  Updated
the generators to account for this.
