Temporary workaround for Roslyn compiler bug

Roslyn doesn't look at inherited true/false operators.

Add #pragma to suppress warning in test case
Fix minor compiler warnings
BamlDecompiler: Correctly qualify types in nested {x:Static} extensions

Includes failing test case
Change Rebracer settings to more closely match current code

The current code is inconsistent in many places; this seems to be the
closest match.
Tests: Reuse decompiler roundtrip assertion code

This contains no functional changes, except that
it will ignore blank lines when comparing code.

This reduces duplicate code, and will make it
easier to add assertions for Roslyn compilers
