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

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.

Change detection of double 0.0 to use BitConverter.DoubleToInt64Bits

Clarify assert assumptions in BetterFunctionMember<TMember> with a comment.

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

#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

#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.

changed the way we calculate appx. solution size.

Our build system currently generates our final output to the Binaries directory but
puts the intermediate output into the source tree in obj directories.  This change unifies
the behavior by putting both intermediate and final output into Binaries.

Remove unnecessary types: ITypeExport, TypeExport

remove subscription to IWorkspaceCacheService from non host workspace.

IWorkspaceCacheService is non-factory MEF workspace service which means it leaves forever. so anything subscribed to it will live forever as well.

this made some temporary workspace to live longer than expected.

Address performance of smart indenter at end of file with inactive regions

Fixes #2641.

Skip custom attribute statistics calculation for EnC deltas

Fixes #3485
Closes #3488

fixed project host cache leak.
