Commit migrated from https://github.com/dotnet/coreclr/commit/c75fee493ec0eb8b4ac57ac3ff69281531218386

Fix x64 perf run break

After the checkin to add legacy JIT testing support for x86 we broke x64
runs.  THe issue is that we do not pass anything in to the TEST_ENV
variable on x64 and when a variable is empty and you attempt to use the
if exists syntax you fail.  I have added a nonsense file name that we
set this to before we go through the args loop. I was not able to find a
better solution and want to get the lab unblocked, but any batch masters
feel free to solve this the right way.

Add perf job for legacy jit

Add performance testing jobs for jit32. This change adds jit32 as an
architecture for perf.groovy. It also renames the x86 legs to be
x86ryujit. For the two x86-based architectures, we pass a testenv. This is
so if we have to switch which version is the default jit on x86, we will
not need to change the perf jobs, we can just update the testenv files.
This change updates run-xunit-perf.cmd to take a test env script as a
parameter and run it before running the tests if it exists.

This change also cleans up some of the calls in perf.groovy to use
variables that we've already set, rather than baking in the contents of
those variables (changing Release to ${configuration}).

Update array length compare value numbers on CSE

Modify CSE to identify compares which are functions of CSE candidate array
length nodes; when those length nodes get CSEd and consequently have their
value numbers updated, also update the value number on the compare
consuming the array length; this way the assertions generated in assertion
prop for the different compares on the CSEd array will use the same value
numbers, and range check elimination becomes more effective.

JIT: Finally chain merging (dotnet/coreclr#8810)

Add an optimization that performs a specialized tail merge for chains
of callfinallys. These can arise from try-finallys where there are
multiple exit points from the try that have the same continuation.

When the jit generates a callfinally, it does so without considering
whether some previously generated callfinally might invoke the same
handler and then continue on to the same continuation.

This optimization looks for callfinallys that invoke the same handler
and have the same continuation and effectively merges them into one
canonical callfinally.

This optimization is done bottom-up (from outermost handler invocation
to innermost) to allow the merging done at an outer levels to enable
merging at inner levels.

This optimization saves code size and also results in more compact EH
reporting, since the callfinallies are reported to the runtime as
duplicate EH regions.

When run upstream of finally cloning, finally chain merging also allows
more of the paths exiting the try to exit via the clone.

Also fix an issue in block ref count maintenance during empty try
removal that caused an assert during finally chain merging.
