[WinEH] Find root frame correctly in CLR funclets

Summary:
The value that the CoreCLR personality passes to a funclet for the
establisher frame may be the root function's frame or may be the parent
funclet's (mostly empty) frame in the case of nested funclets.  Each
funclet stores a pointer to the root frame in its own (mostly empty)
frame, as does the root function itself.  All frames allocate this slot at
the same offset, measured from the post-prolog stack pointer, so that the
same sequence can accept any ancestor as an establisher frame parameter
value, and so that a single offset can be reported to the GC, which also
looks at this slot.

This change allocate the slot when processing function entry, and records
its frame index on the WinEHFuncInfo object, then inserts the code to
set/copy it during prolog emission.

The intention is that InstCombine's BSWAP detection logic will be extended to support BITREVERSE too, and @llvm.bitreverse intrinsics emitted (if the backend supports lowering it efficiently).

which consume a token and produce a new token.  Currently, we have no
mechanism to represent an initial token state.

Instead, we can create a notional "empty token" by inventing a new

LLVM can recognize and optimize these in more precise ways than it can a
generic "unknown" operand bundles.

The current form of this special recognition / optimization is an enum

will teach LLVM to do more aggressive optimization around deoptimization
