[x86] be more selective about converting 'and' to shuffle (PR37749)

isVectorClearMaskLegal() is the TLI hook used by the generic
DAGCombiner::XformToShuffleWithZero().

We've grown to accomodate/expect this transform to shuffle
(disabling it more generally results in many regressions).
So I'm narrowly excluding the 256-bit types that clearly
are not worthwhile for AVX1.

I think in most cases we are able to recover by converting
the shuffle back into 'and' ops, but the cases in:

[DAG] Avoid needing to walk out legalization tables. NFCI.

To avoid redundant work, during DAG legalization we keep tables
mapping pre-legalized SDValues to post-legalized SDValues and a
SDValue-to-SDValue map to enable fast node replacements. However, as
the keys are nodes which may be reused it is possible that an entry in
a table refers to a now deleted node N (that should have been renamed
by the value replacement map) while a new node N' exists. If N' is
then replaced that entry would be wrong. Previously we avoided this by
when potentially violating this property, walking every table and
updating all node pointers. This is very expensive but hopefully rare
occurance.

This patch assigns each instance of a SDValue used in legalization a
unique id and uses these ids in the legalization tables. This avoids
any such aliasing issue, avoiding the full table search and allowing
more aggressive incremental table pruning.

DebugNamesDWARFIndex: fix handling of compressed sections

This fixes a silly bug where we were accidentally freeing the memory
used to store the decompressed .debug_names data. I had actually
considered this scenario when writing the class and put appropriate
precautions in place -- I just failed to wire it all up correctly.

This was only an issue for compressed sections because in case of
uncompressed ones we would access the data straight out of the mmapped
object file.

[DWARFv5] Tolerate files not all having an MD5 checksum.

In some cases, for example when compiling a preprocessed file, the
front-end is not able to provide an MD5 checksum for all files. When
that happens, omit the MD5 checksums from the final DWARF, because
DWARF doesn't have a way to indicate that some but not all files have
a checksum.

When assembling a .s file, and some but not all .file directives
provide an MD5 checksum, issue a warning and don't emit MD5 into the
DWARF.

Fixes PR37623.
