	* *.cs: Major rewrite of compiler internals to better work with
	unmodified System.Reflection.Emit. Some of the key changes are
	- TypeSpec replaces reflection specific System.Type.
	- All Type(TypeSpec) operations are now done in compiler therefore
	no dependency on SRE to inflate generic members and types or to
	query unclosed types.
	- MemberCache is now the only and full hierarchical topology.
	- Generic constraints are implemented properly.
	- And as a bonus compilation is on average 30% faster.
