This reverts commit 265a38fb.

My editor keeps on changing this and I keep having to revert it.

Make it possible to inspect the matched node, possibly to ignore it.

- Change syntax for FuncOp to be `func <visibility>? @name` instead of printing the
  visibility in the attribute dictionary.
- Since printFunctionLikeOp() and parseFunctionLikeOp() are also used by other
  operations, make the "inline visibility" an opt-in feature.
- Updated unit test to use and check the new syntax.

Add a TLI hook to allow SelectionDAG to fine tune the conversion of CTPOP to a chain of "x & (x - 1)" when CTPOP isn't legal.

A subsequent patch will attempt to fine tune the X86 code gen.

There is not reason to check `std::make_unique<...>(..)` return value,
but `clangd::clang::loadIndex()` returns `nullptr` if an index file could not be loaded (e.g. incorrect version).

MachO has different symbol naming and thus on a MachO platform this test has a
different behavior without a triple.

For example if the sign extension is only used in for TBZ, and the value is used elsewhere with a zero extension, this can eliminate a sign extension.

This was accidentally using the same name for two different variables in
the same line. Whilst it seems to work for some compilers, others have
trouble and it is probably not a fantastic idea.

I don't have a Windows machine. Hope someone can test why its InputSection is
still larger.

This uses the shiftop PatFrags to handle the masked shift amount
and unmasked shift amount cases. That also checks XLen as part
of the masked amount check so we don't need separate RV32 and RV64
patterns.

On LP64/Windows platforms, this decreases sizeof(InputSection) from 208 (larger
on Windows) to 184.

For a large executable (7.6GiB, inputSections.size()=5105122,
make<InputSection> called 4835760 times), this decreases cgroup
memory.max_usage_in_bytes by 0.6%

Just use default CHECK

FastISel generates instructions to materialize "local values" at the
top of a block, in the hope that these values could be reused within
the block.  To reduce spills and restores, FastISel treats calls as
sub-block boundaries, flushing the "local value map" at each call.

This patch treats the mem* intrinsics as if they were calls, because
at O0 generally they are calls.  Eliminating these spills/restores is
actually better for debugging (especially a "continue at this line"
command), code size, stack frame size, and maybe even performance.

This reverts commit df30bc01.

This revision adds support for bufferization by using a mix of `tensor_load`, `subview`, `linalg.copy` and `tensor_to_memref`.

During active replay, the ::Initialize call is replayed like any other
SB API call and the return value is ignored. Since we can't intercept
this, we terminate here before the uninitialized debugger inevitably
crashes.
