Currently compiler assert when passing variable "memspace" in
omp_init_allocator.

omp_allocator_handle_t alloc=omp_init_allocator(memspace,1,traits)

The problem is memspace is not mapping to the target region.  During
the call to emitAllocatorInit, calls to EmitVarDecl for "alloc", then
emit initialization of "alloc" that cause to assert.

If I understant correct, it is not necessary to emit variable
initialization, since "allocator" is private to target region.

To fix this call CGF.EmitAutoVarAlloca(allocator) instead
CGF.EmitVarDecl(allocator).

In ProcessMachCore::LoadBinariesViaMetadata(), if we did
load some binaries via metadata in the core file, don't
then search for a userland dyld in the corefile / kernel
and throw away that binary list.  Also fix a little bug
with correctly recognizing corefiles using a `main bin spec`
LC_NOTE that explicitly declare that this is a userland
corefile.

LocateSymbolFileMacOSX.cpp's Symbols::DownloadObjectAndSymbolFile
clarify the comments on how the force_lookup and how the
dbgshell_command local both have the same effect.

In PlatformDarwinKernel::LoadPlatformBinaryAndSetup, don't
log a message unless we actually found a kernel fileset.

Reorganize ObjectFileMachO::LoadCoreFileImages so that it delegates
binary searching to DynamicLoader::LoadBinaryWithUUIDAndAddress and
doesn't duplicate those searches.  For searches that fail, we would
perform them multiple times in both methods.  When we have the
mach-o segment vmaddrs for a binary, don't let LoadBinaryWithUUIDAndAddress
load the binary first at its mach-o header address in the Target;
we'll load the segments at the correct addresses individually later
in this method.

DynamicLoaderDarwin::ImageInfo::PutToLog fix a LLDB_LOG logging
formatter.

In DynamicLoader::LoadBinaryWithUUIDAndAddress, instead of using
Target::GetOrCreateModule as a way to find a binary already registered
in lldb's global module cache (and implicitly add it to the Target
image list), use ModuleList::GetSharedModule() which only searches
the global module cache, don't add it to the Target.  We may not
want to add an unstripped binary to the Target.

Add a call to Symbols::DownloadObjectAndSymbolFile() even if
"force_symbol_search" isn't set -- this will turn into a
DebugSymbols call / Spotlight search on a macOS system, which
we want.

Only set the Module's LoadAddress if the caller asked us to do that.

When printing the root of a value, if it's a reference its children are unconditionally
printed - in contrast to pointers whose children are only printed if a sufficient
pointer depth is given.

However, the children are printed even when there's a summary provider that says not to.
If a summary provider exists, this change consults it to determine if children should be
printed.

For example, given a variable of type `std::string &`, this change has the following
effect:

Before:

```
(lldb) p string_ref
(std::string &) string_ref = "one two three four five six seven eight nine ten": {
  __r_ = {
    std::__1::__compressed_pair_elem<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> >::__rep, 0, false> = {
      __value_ = {
         = {
          __l = (__data_ = "one two three four five six seven eight nine ten", __size_ = 48, __cap_ = 64, __is_long_ = 1)
          __s = (__data_ = "@\0p\U00000001\0`\0\00\0\0\0\0\0\0\0@", __padding_ = "\x80t<", __size_ = '\0', __is_long_ = '\x01')
          __r = {
            __words ={...}
          }
        }
      }
    }
  }
}
```

After:

```
(lldb) p string_ref
(std::string &) string_ref = "one two three four five six seven eight nine ten"

This is a major step along the way towards the new STEA design.  While a great deal of this patch is simple renaming, there are several significant changes as well.  I've done my best to ensure that this patch retains the previous behavior and error-conditions, even though those are at odds with the eventual intended semantics of the `dimToLvl` mapping.  Since the majority of the compiler does not yet support non-permutations, I've also added explicit assertions in places that previously had implicitly assumed it was dealing with permutations.

These are additional tests for D151596.

This patch introduces FileSpec::GetComponents, a method that splits a
FileSpec's path into its individual components. For example, given
/foo/bar/baz, you'll get back a vector of strings {"foo", "bar", baz"}.

The motivation here is to reduce the use of
`FileSpec::RemoveLastPathComponent`. Mutating a FileSpec is expensive,
so providing a way of doing this without mutation is useful.

This is more consistent with how we handle integer widening multiply.

A follow up patch will add support for matching vfwmul when the
multiplicand is being squared.

This patch adds support for `tosa.scatter` lowering in the `--tosa-to-scf` pass. Here's an example for this lowering:

```
func.func @tosa(
                %valuesIn : tensor<3x7x5xi32>,
                %indices : tensor<3x6xi32>,
                %input : tensor<3x6x5xi32>) ->
                tensor<3x7x5xi32> {
        %0 = "tosa.scatter"(%valuesIn, %indices, %input) :
                        (tensor<3x7x5xi32>,
                        tensor<3x6xi32>,
                        tensor<3x6x5xi32>) ->
                        (tensor<3x7x5xi32>)
        return %0 : tensor<3x7x5xi32>
}
```

translates to
  func.func @tosa(%arg0: tensor<3x7x5xi32>, %arg1: tensor<3x6xi32>, %arg2: tensor<3x6x5xi32>) -> tensor<3x7x5xi32> {
    %c0 = arith.constant 0 : index
    %c3 = arith.constant 3 : index
    %c1 = arith.constant 1 : index
    %c6 = arith.constant 6 : index
    %c2 = arith.constant 2 : index
    %c5 = arith.constant 5 : index
    %c0_0 = arith.constant 0 : index
    %c1_1 = arith.constant 1 : index
    %0 = scf.for %arg3 = %c0_0 to %c3 step %c1_1 iter_args(%arg4 = %arg0) -> (tensor<3x7x5xi32>) {
      %1 = scf.for %arg5 = %c0_0 to %c6 step %c1_1 iter_args(%arg6 = %arg4) -> (tensor<3x7x5xi32>) {
        %extracted = tensor.extract %arg1[%arg3, %arg5] : tensor<3x6xi32>
        %2 = arith.index_cast %extracted : i32 to index
        %extracted_slice = tensor.extract_slice %arg2[%arg3, %arg5, %c0_0] [%c1_1, %c1_1, %c5] [%c1_1, %c1_1, %c1_1] : tensor<3x6x5xi32> to tensor<?x?x?xi32>
        %inserted_slice = tensor.insert_slice %extracted_slice into %arg6[%arg3, %2, %c0_0] [%c1_1, %c1_1, %c5] [%c1_1, %c1_1, %c1_1] : tensor<?x?x?xi32> into tensor<3x7x5xi32>
        scf.yield %inserted_slice : tensor<3x7x5xi32>
      }
      scf.yield %1 : tensor<3x7x5xi32>
    }
    return %0 : tensor<3x7x5xi32>
  }
```

We have attempted an alternative lowering pass that uses `tensor.scatter` as an intermediate step. However, we opted to aim straight at the `scf` dialect for the following reasons:

- The `tensor.scatter` op doesn't seem to be used anywhere. There is no available lowering pass for this op (although we have one that we'll upstream soon).
- The `tosa.scatter` and `tensor.scatter` op have different indexing semantics. The `indices` argument of `tosa.scatter` must be non-trivially modified and restructured (e.g. with a `linalg.generic` op) to adapt to the needs of `tensor.scatter`. While this overhead may be simplified and fused after a subsequent `tensor.scatter` lowering, it adds complex logic and an obscure intermediate state. Unless there is a good reason to go through the `tensor` dialect that we're missing, this additional complexity may not be justified.
