Don't add nop padding for rejitting a funclet prolog.

This is along standing issue in RyuJit. When ngenning the crossgen tool
passes CORJIT_FLG_PROF_REJIT_NOPS flag. The padding for rejitting should
be added only for the main function and not the funclets when compiling a
method. Trying to generate a rejit padding for a funclet in debug and
checked build results in a failing assertion.

Fixes issue 3601.

ARM64: Running cmd instead of exe

Our test framework (smarty) directly runs test executable on corerun.exe.
But some of tests expect arguments via environment variable specified in .cmd.
The fix is to change the test list file to run .cmd. So the expected pass
value is also updated to 0 instead of 100. Now we don't need to pass /host

Make sure 4 outgoing arg slots are generated for methods that call
THROW_HELPERS for Windows x64.

This is a long standing bug in RyuJit.
When compiling a method for debug mode if there is a call to THROW_HELPER
(and it is the only call) the frame for the method that calls the
THROW_HELPER is not properly set - it is missing the 4 ougoing arg slots.

This was discovered by R2R codegen. In normal jitting of such method in
debug mode the jit always adds a call to CORINFO_HELP_DBG_IS_JUST_MY_CODE
early enough, so the frame size will be properly calculated. This call is
not generated for R2R.

If the method generated for R2R has only a call to a throw helper
and it is compiled for debug mode, the call is not generated in the IR.
The CodeGen generates the call directly instead. The call is generated
after the stack frame is calculated. This leads to improperly generated
stack frame that doen't have the 4 outgoing arg slots that the Windows x64
ABI requires.

Compiling such method for release mode is never a problem since in
FlowGraph we always generate IR for a block that contains the
THROW_HELPER. This happens before the stack frame is calculated, so the 4
outgoing stack slots are always calculated.

ARM64: Fix Frame with compLocallocUsed

When compLocallocUsed is true, stack pointer is changed during the run.
So, JIT should restore stack pointer from frame pointer in the epilog.
Previously, we simpliy copied fp to sp, which is only valid for frameType
= 1.
This implements a right restoring process for other frameTypes (2 and 3).
For frameType = 3, I also simplified creating prolog sequence to support
this feature consistently.

objcopy: Support cross-build for stripping symbols

Currently, the 'objcopy' does only support native-build since
the commit number dotnet/coreclr@4efef62f0ead16b4f8ca2c6ccf0a77ce112f73b9
Let's add cross-build as well as native-build to strip symbols.

v3:
- support if statement for arm64

v2:
- Replace 'EQUAL' with 'DEFINED' for handling Other Linux distributions
  as well as Ubuntu 14.04 and for handling in case of native-build.

v2:
- support cross-build to strip debug symbols of native arm binaries

Unsuppress same-reg zero-extending mov (x64)

Update CodeGen::genIntToIntCast to stop suppressing 32-bit same-register
`mov`s, and to stop assuming that 32-bit enregistered sources already have
the top half of their register clear.  This latter assumption is usually
true, but is not guaranteed across function boundaries by the ABI.  As it
happens, the runtime code that invokes custom attribute constructors can
pass garbage in the top half of such parameters; this change adds a
testcase that fails on that path without this fix.

Inliner: refactor policies to extract common legality portion

Now that we have multiple policies, refactor their implementation
to extract common elements. In particular all the existing
policies have the same legality and ability constraints, so this
logic is extracted to a partial `LegalPolicy` superclass.

Adresses relevant feedback on dotnet/coreclr#3697, where the number of policies
increased from one to two.

No changes in behavior.
