Do not allocate too much for Guid stream

Trim the filepaths in FindRefs to avoid displaying so much redundant information.

Collect a trace during BasicPerfRenameRoslyn

This change removes two obsolete types:

- MetadataCache
- MetadataFileReference

This types were obsolete and used only in testing.

Update all projects to reference Microsoft.DiaSymReader 1.0.3-rc2...

Revert accidentally changed casing in resource file

Indent/Format Auto Property Initializers appropriately

Add missing references to DiaSymReader to test assemblies

Proposal: Consolidate ResultProvider resources

The language-specific resource files have only one entry each. Just move
them into the shared resource file so that we will only need a single
satellite assembly.

Fix #1339 : Indent the initializer of the Auto Property one less than
the beginning of the statement to signify the initializer is still part
of the Property declaration when issued a <Return> just before Auto
Property Initializer

If the user has selected a custom indentation for the Auto Property
Initializer don't distrub it and preserve the spaces

Handle pseudo-variables with pointer types

Introduce a hoisted local scope abstraction

Since hoisted locals are fields, they are in scope throughout the entire
method body.  However, from the user's perspective, they are still locals,
so we attempt to retain their original scopes during debugging.
Unfortunately, C# and VB use different mechanisms for doing so.  In order
to make the code more consistent, and to simplify consumption of the new
PDB format (which is more similar to C#), we introduce an abstract type
InScopeHoistedLocals that represents the set of in-scope hoisted locals in
a consistent way in both languages (and both PDB formats).

Fix for failing compiler server test SimpleMSBuild, that uses Roslyn msbuild tasks.

Add "ErrorLog" and "ReportAnalyzer" properties to our build tasks for the corresponding properties added to Microsoft.CSharp.CurrentVersion.targets and Microsoft.VisualBasic.CurrentVersion.targets.

The intrinsic methods that we call to retrieve the values of
pseudo-variables from the debugger return System.Object.  Unfortunately,
object cannot be converted (directly) to a pointer type.  Instead, we need
to unbox an IntPtr and then call an explicit conversion method to get a
pointer.

Caveat: This won't work until the debugger actually returns a boxed
IntPtr.

Pointer types can appear in assembly-qualified names (AQNs).  Our encoding
mechanism handles them, but our decoding mechanism does not.

Caveat: We now support arrays of pointers, but not pointers to arrays
(since neither C# nor VB supports such types).

Merge anonymous types differing by case in VB EnC

Replace PdbOutputInfo with EmitStreamProvider

Ordering of anonymous type definitions should be deterministic

Add "ErrorLog" and "ReportAnalyzer" properties to our build tasks for the corresponding properties added to Microsoft.CSharp.CurrentVersion.targets and Microsoft.VisualBasic.CurrentVersion.targets.

Now that the comment formatting issue is fixed in the Formatter type, we can run the formatter on the remainder of the VB code base.
