[AArch64][SVE] Support implicit lax vector conversions for SVE types

[mlir] Add basic support for attributes in ODS-generated Python bindings
In ODS, attributes of an operation can be provided as a part of the "arguments"
field, together with operands. Such attributes are accepted by the op builder
and have accessors generated.
Implement similar functionality for ODS-generated op-specific Python bindings:
the `__init__` method now accepts arguments together with operands, in the same
order as in the ODS `arguments` field; the instance properties are introduced
to OpView classes to access the attributes.
This initial implementation accepts and returns instances of the corresponding
attribute class, and not the underlying values since the mapping scheme of the
value types between C++, C and Python is not yet clear. Default-valued
attributes are not supported as that would require Python to be able to parse
C++ literals.
Since attributes in ODS are tightely related to the actual C++ type system,
provide a separate Tablegen file with the mapping between ODS storage type for
attributes (typically, the underlying C++ attribute class), and the
corresponding class name. So far, this might look unnecessary since all names
match exactly, but this is not necessarily the cases for non-standard,
out-of-tree attributes, which may also be placed in non-default namespaces or
Python modules. This also allows out-of-tree users to generate Python bindings
without having to modify the bindings generator itself. Storage type was
preferred over the Tablegen "def" of the attribute class because ODS
essentially encodes attribute _constraints_ rather than classes, e.g. there may
be many Tablegen "def"s in the ODS that correspond to the same attribute type
with additional constraints
The presence of the explicit mapping requires the change in the .td file
structure: instead of just calling the bindings generator directly on the main
ODS file of the dialect, it becomes necessary to create a new file that
includes the main ODS file of the dialect and provides the mapping for
attribute types. Arguably, this approach offers better separability of the
Python bindings in the build system as the main dialect no longer needs to know
that it is being processed by the bindings generator.

[scudo][standalone] Correct min/max region indices
The original code to keep track of the minimum and maximum indices
of allocated 32-bit primary regions was sketchy at best.
`MinRegionIndex` & `MaxRegionIndex` were shared between all size
classes, and could (theoretically) have been updated concurrently. This
didn't materialize anywhere I could see, but still it's not proper.
This changes those min/max indices by making them class specific rather
than global: classes are locked when growing, so there is no
concurrency there. This also allows to simplify some of the 32-bit
release code, that now doesn't have to go through all the regions to
get the proper min/max. Iterate and unmap will no longer have access to
the global min/max, but they aren't used as much so this is fine.

lld/mach-o: Infer darwinnew from filename ld64.lld.darwinnew too
`-flavor` is difficult to use through the clang driver since it
must be the first argument.
clang's `-fuse-ld=foo` looks for `ld64.foo` when targeting darwin,
so it's easiest if darwinnew accepts some `ld64.foo`. Let's go with
`ld64.lld.darwinnew`, so that `clang -fuse-ld=lld.darwinnew` does
the right thing (assuming a symlink with the name `ld64.ld.darwinnew
exists in the right place).
This is temporary until darwinnew replaces ld64.lld, and it only
exists to make testing the new lld port easier.

[SCEV] Factor out part of wrap flag detection logic [NFC](try 2)
This is a cut down version of 1ec6e1 which was reverted due to a compile time issue. The key changes made from that patch: 1) only infer the flags needed along each path, 2) be careful to preserve order of checks, and 3) avoid computing NW flags at all since we need to prove the stronger property (does not cross 0) in the caller anyways.
Assuming this doesn't trip regressions, I'm going to try weakening (1). My end objective is to move flag inference into addrec construction. If I can't weaken (1) without compile time impact, I'll have a problem.
