[builtins] Only build float16/bfloat16 code if actually supported
When building compiler-rt builtins for x86_64 they library will by default
also be built for i386. We unconditionally add the Float16 compile flags
since the check for Float16 support will be done using x86_64 compiler
flags, but i386 does not actually support it. Fix this by moving the
COMPILER_RT_HAS_FLOAT16 and COMPILER_RT_HAS_FLOAT16 checks to a
per-target-architecture check inside the loop (using
`check_c_source_compiles` and `cmake_{push,pop}_check_state`).
Many of the checks in the builtin-config-ix file should probably also be
changed to per-target-arch checks, but so far only the Float16 one has
caused issues. This is an alternative to D136044 which added a special case
for i386 FreeBSD.

[mlir][linalg] Refine how contiguous loads are identified
Vectorization of `tensor.extract` using contiguous loads
(`vector.transfer_read`) was introduced in [1]. This patch updates and
refines the existing logic (so that more cases of contiguous can be
identified), as well as adds more tests.
Specifically, contiguous load operations are identified by making sure
that:
1. non-trailing indices for `tensor.extract` are loop invariant (so,
e.g., there are no "jumps" from one row to the other between
iterations),
2. the trailing index for `tensor.extract` increments by 1 with every
loop iteration (so that it's always adjacent elements that are
loaded).
This patch introduces:
* `isLoopInvariantIdx` for step 1., and
* `isContiguousLoadIdx` for step 2.
These new methods replace:
* `isContiguousLoadIdx`, and `isBasedOnIndexOp`.
Both approaches lead to similar end-result (none of the existing tests
required updating). However, with the updated approach, it's much easier
to treat the trailing and non-trailing indices separately and to add
more cases for which contiguous loads can be used.

Recommit "[lldb] Redefine p alias to dwim-print command"
Redefine the `p` alias to the `dwim-print` command instead of `expression`.
See https://reviews.llvm.org/D138315 for the introduction of `dwim-print`.
To summarize, `dwim-print` is, as the name suggests, a command for printing. How a value
gets printed, is decided by `dwim-print`. In some cases, `dwim-print` will print values
using the same means as `frame variable` (because it's generally more reliable and
faster that `expression` evaluation), and in other cases `dwim-print` uses the same code
path as `expression`.
This change has been tested in two different ways:
1. Re-aliasing `p` to `dwim-print`, as in this patch
2. Redefinining the `expression` command to `CommandObjectDWIMPrint`
Previously, many of the lldb's tests used `p`, and which meant a test run with `p`
aliases to `dwim-print` was a good way to test `dwim-print`. However most of those tests
were updated to use `expression` explicitly (in anticipation of this change). Now, the
best way to test `dwim-print` is the second approach:
```
diff --git a/lldb/source/Interpreter/CommandInterpreter.cpp b/lldb/source/Interpreter/CommandInterpreter.cpp
index
373c894f34f5..
9c943cd30c7c 100644

REGISTER_COMMAND_OBJECT("frame", CommandObjectMultiwordFrame);
REGISTER_COMMAND_OBJECT("gui", CommandObjectGUI);
REGISTER_COMMAND_OBJECT("help", CommandObjectHelp);
```
When the test suite is run with this change, there are two main categories of test
failures for specific to features that `dwim-print` intentionally doesn't support:
1. Top level expressions (`--top-level`/`-p`)
2. Multiline expressions
In cases where the behavior of `expression` is needed, users can use `expression` at
those times.

Error diagnostics captured in exceptions aren't propagated to diagnostic
handlers, to avoid double-reporting of errors. The context-level
`emit_error_diagnostics` option can be used to revert to the old
behaviour, causing error diagnostics to be reported to handlers instead
of as part of exceptions.
API changes:
- `Operation.verify` now raises an exception on verification failure,
instead of returning `false`
- The exception raised by the following methods has been changed to
`MLIRError`:
- `PassManager.run`
- `{Module,Operation,Type,Attribute}.parse`
- `{RankedTensorType,UnrankedTensorType}.get`
- `{MemRefType,UnrankedMemRefType}.get`
