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.

Enable delay signing in ilasm

Corefx needs the .Net Core version of ilasm to create delay signable
assemblies. This change brings back AllocateStrongNameSignature that was
deleted in 2efbb92 and modifies it to use similar logic from Roslyn to
determine the size of the signature that we need to allocate space for.

Fixes dotnet/coreclr#9292.

JIT: null out inline gc type locals after inline body

Inlining can sometimes end up stretching GC lifetimes for inlinee
locals past the end of the inlinee method body.

This change extends the work done for inlining methods with pinned
locals to null out all gc ref type locals. If there are any gc type
locals, the return value is copied to a temp inside the inlinee body,
and then at the end of the body the gc type locals are set to null.

In most cases these null stores end up getting removed by dead code
elimination, but if the local ends up untracked, the store remains
and limits the active GC lifetime.

This change requires more extensive use of the return value spill temp
(since we must be absolutely sure the return value expression does not
depend on any of the locals). We now use the spill temp if any local is
a gc ref type (used or not).

More widespread use of the spill temp exposed an issue in the tail call
transformation, where the side effect flags were overly pessimistic for
a post tail-call GT_COMMA statement that represented an ignored return
value from an inlined call. The root issue is that the return value
placeholder is given a GTF_CALL effect but later when the actual return
value expression is substituted in place there may be no side effect --
in particular this happens when the return value expression is the spill
temp.

So, we also update the post tail-call side-effect-free statment check to
look through the potentially pessimistic GT_COMMA flags and check for side
effects on the child nodes.

Closes dotnet/coreclr#9218.

Jit: fix gtIsRecursiveCall

When called from the inline compiler, this needs to look at the root
method's handle, not the inlined method's handle.

Fixes dotnet/coreclr#9568.

Add IR size after certain phases to the JIT log.

This change adds support for measuring and reporting the number of nodes
in a function after a certain subset of the JIT's phases. This reporting
is enabled by setting `COMPlus_JitMeasureIR` and `COMPlus_JtiTimeLogCsv`
in conjunction with each other.

Rejit support for R2R images

Two changes:
a) R2R code wasn't being reported to the Rejit Manager when it was used, this is a simple fix in prestub.cpp. This makes the ReJit API work.
b) The bulk of the changes handle adding support for an inlining table to R2R so that ICorProfilerInfo6::EnumNgenMethodsInliningThisMethod can supply that information to profilers.

This was only tested on Windows thus far, but there is no apparent reason this change would be OS specific.
