Sebastien Pouliot e72b654890 [linker] Inline BinaryCompatibility.TargetsAtLeast_Desktop_V4_5[_1] (#1518) 
This is a more interesting case since the inlining of 2 property getters
has a deeper impact and removes other types/methods from the final app.

Here we don't care what's inside the code we replace - only that it
always return a constant boolean after evaluation. That _constant_ is
something we can add tests to ensure we continue to behave identically.

Q: Why some stuff is not linked out ?

A: In most case this is because:
	a) the BCL uses it internally
	b) the mono runtime depends on the type, methods, class layout


= mscorlib.dll =

System.Security.PermissionSet
	* Assembly has (3) fields of that type
	* mscorlib.xml preserve all fields from Assembly (object-internals.h)
	* code is "stubified" by the linker
System.Security.Policy.ApplicationTrust: 
	* Used as a field in AppDomainSetup;
	* Field also exists in unmanaged code (domain-internals.h);
	* mscorlib.xml preserve all fields from AppDomainSetup
	* only the default .ctor remains and is stubified by the linker
System.Security.Policy.Evidence
	* Used by AppDomain.Load[Assembly]
	* Used by Assembly.LoadWithPartialName overloads
	* code is "stubified" by the linker


= System.dll =

System.Text.RegularExpressions.*
	* Included because there is 2 regex in UriParser
