Even within a multiclass, we had been generating concrete implicit anonymous
defs when parsing values (generally in value lists). This behavior was
incorrect, and led to errors when multiclass parameters were used in the
parameter list of the implicit anonymous def.

If we had some multiclass:

multiclass mc<string n> {

 ... : SomeClass<SomeOtherClass<n> >

The capture of the multiclass parameter 'n' would not work correctly, and
depending on how the implicit SomeOtherClass was used, either TableGen would
ignore something it shouldn't, or would crash.

To fix this problem, when inside a multiclass, we generate prototype anonymous
defs for implicit anonymous defs (just as we do for explicit anonymous defs).
Within the multiclass, the current record prototype is populated with a node
that is essentially: !cast<SomeOtherClass>(!strconcat(NAME, anon_value_name)).
This is then resolved to the correct concrete anonymous def, in the usual way,
when NAME is resolved during multiclass instantiation.

A ValueType in a pattern dag is a type cast, and GetNumNodeResults should
handle it (the type cast has only one result).

This comes up, for example, during the type checking of pattern fragments, for
example, AArch64's Neon_combine_2d fragment is:
  dag Operands = (ops node:$Rm, node:$Rn);
  dag Fragment = (v2f64 (concat_vectors (v1f64 node:$Rm), (v1f64 node:$Rn)));

Plugins need to go in build/Debug/lib as well (rather than build/lib/Debug).

Also, fix the SHLIBDIR path for Xcode, which by default includes Xcode build

TableGen had been generating a different name for an anonymous multiclass's
NAME for every def in the multiclass. This had an unfortunate side effect: it
was impossible to reference one def within the multiclass from another (in the
parameter list, for example). By making sure we only generate an anonymous name
once per multiclass (which, as it turns out, requires only changing the name
parameter to reference type), we can now concatenate NAME within the multiclass
with a def name in order to generate a reference to that def.

This does not matter so much, in and of itself, but is necessary for a
follow-up commit that will fix variable capturing in implicit anonymous
multiclass defs (and that is important).

When widening an IV to remove s/zext, we generally try to eliminate
the original narrow IV. However, LCSSA phi nodes outside the loop were
still using the original IV. Clean this up more aggressively to avoid
redundancy in generated code.

In a standalone build, Clang binaries should end up in Clang's build folder,
not LLVM's.

Xcode still has a few issues finding auxiliary tools and libraries in the

The separate Xcode project generated for Clang is putting the clang
executables into the same location where the LLVM executables are
going. This is wrong, and breaks the Clang build because we try to
create clang++ and clang-cl symlinks in the wrong place and to the
wrong place.

As a stop-gap to get these builds working again, teach the symlink
generation to point into the LLVM executable directory instead.
