I don't have a reduced test case, but for a version of FFMPEG, this

running, it hadn't terminated for me, no idea if it was a true infloop
or just exponential work).

The key thing here is to check the DeadInstructions set when pulling
things off the worklist. Without this, we would re-walk the user list of
already dead instructions again and again and again. Consider phi nodes
with many, many operands and other patterns.

The other important aspect of this is that because we would keep
re-visiting instructions that were already known dead, we kept adding
their cost savings to this! This would cause our cost savings to be
*insanely* inflated from this.

While I was here, I also rotated the operand walk out of the worklist
loop to make the code easier to read. There is still work to be done to
minimize worklist traffic because we don't de-duplicate operands. This
means we may add the same instruction onto the worklist 1000s of times
if it shows up in 1000s of operansd to a PHI node for example.

Still, with this patch, the ffmpeg testcase I have finishes quickly and
I can't measure the runtime impact of the unroll analysis any more. I'll
probably try to do a few more cleanups to this code, but not sure how

This seems like a poor man's assertion that the arrays do eventually get
replaced.  These days, temporaries in the graph will cause assertions
when writing bitcode or assembly, so this isn't necessary.  Use
temporary empty tuples instead.

Note that the whole idea of using temporaries and then replacing them
later is wasteful here.  We never actually want to merge compile units
by uniquing based on content.  Compile units should use `getDistinct()`
instead of `get()`, and then their operands can be freely replaced later

[TTI] Teach the cost heuristic how to query TLI to check if a zext/trunc is 'free' for the target.

how to query TLI in order to get a more accurate cost for truncates and

Before this patch, the basic cost heuristic in TargetTransformInfoImplCRTPBase
would have conservatively returned a 'default' TCC_Basic for all zero-extends,
and TCC_Free for truncates on native types.

This patch improves the heuristic so that we query TLI (if available) to get
more accurate answers. If TLI is available, then methods 'isZExtFree' and
'isTruncateFree' can be used to check if a zext/trunc is free for the target.

Added more test cases to SimplifyCFG/X86/speculate-cttz-ctlz.ll.
With this change, SimplifyCFG is now able to speculate a 'cheap' cttz/ctlz
immediately followed by a free zext/trunc.
