Tried with Moq and some tests failed

[informatorius]

I tried to use FastExpressionCompiler inside Moq source code replacing all Compile() calls with CompileFast(). Most Moq.Tests succeeded but some failed.

Let's fix them then :) What tests?
Ideally, could you add failing and ignored tests into FEC.IssueTests.

1. Download https://github.com/moq/moq4 latest
2. Build all
3. Run Moq.Tests
   => 1000 tests succeeded
4. Edit 5 moq source files which use Expression.Compile() and replace with Expression.CompileFast()
5. Build all
6. Run Moq.Tests again
   => 4 out of 1000 tests failed

Thanks for the steps! Btw, not bad :)
I would expect more tests to fail.

It is good work so far. Guess not all tests use Expression.Compile()
