While running managed debugger tests with x86 runtime debug build, I was
hiting an assert in MachineState::pRetAddress() method in a couple of
tests.
It turns out there was a bug in the HelperMethodFrame::UpdateRegDisplay
introduced about 5 years ago that only happens in DAC. The m_MachState
can be uninitialized when we enter the method and we were calling
m_MachState.pRetAddr() before performing the initialization.

This change fixes it.

Turns out this particular test doesn't actually need process
isolation, I overzealously marked it as such in a previous wave
just because it's a static initialization test. This lets us
postpone dealing with out-of-process ilproj tests to a later
phase.

Thanks

When building tests in merged mode, we need to copy the native
references along with the component test dlls to the output folder
to make them discoverable by the OS loader.

Thanks

Tomas
