The tosa-infer-shapes pass crashes when trying to infer the output shape
of tosa.equal when the input shape is unranked.
This is due to tosa-infer-shapes requiring at least information on the
base type of the resulting operation from inferReturnTypeComponents.
This change enhances EqualOp::inferReturnTypeComponents to always supply
the inferred elementType.

This reduces dependencies on `llvm-tblgen` so much.
`CodeGenTypes` depends on `Support` at the moment.
Be careful to append deps on this, since Targets' tablegens
depend on this.

This is rework of;
- rG13e77db2df94 (r328395; MVT)
Since `LowLevelType.h` has been restored to `CodeGen`, `MachinveValueType.h`

This is rework of;
- D30046 (LLT)
Since I have introduced `llvm-min-tblgen` as D146352, `llvm-tblgen`
may depend on `CodeGen`.
`LowLevlType.h` originally belonged to `CodeGen`. Almost all userse are
still under `CodeGen` or `Target`. I think `CodeGen` is the right place
to put `LowLevelType.h`.
`MachineValueType.h` may be moved as well. (later, D149024)
I have made many modules depend on `CodeGen`. It is consistent but
inefficient. It will be split out later, D148769
Besides, I had to isolate MVT and LLT in modmap, since
`llvm::PredicateInfo` clashes between `TableGen/CodeGenSchedule.h`
and `Transforms/Utils/PredicateInfo.h`.
(I think better to introduce namespace llvm::TableGen)
Depends on D145937, D146352, and D148768.

This reverts commit e3b1083e00.
This was reverted because it breaks a number of libstdc++ examples, AND
required a workaround that causes hiding of legitimate bugs.
After importing variables, we do some checking to ensure that variables
marked read or write only, which have been marked exported (e.g.
because a referencing function has been exported), are on at least one
module's imports list. This is because the read or write only variables
will be internalized, so we need a copy any any module that references
it.
This checking is overly conservative in the case of linkonce_odr or
other linkage types where there can already be a duplicate copy in
existence in the importing module, which therefore wouldn't need to
import it. Loosen up the checking for these linkage types.

The MLIR SVE integration tests are now enabled in the
clang-aarch64-full-2stage buildbot under emulation (QEMU) and two of the
sparse integration tests are failing [1]:
* mlir/test/Integration/Dialect/SparseTensor/CPU/sparse_sorted_coo.mlir
* mlir/test/Integration/Dialect/SparseTensor/CPU/sparse_spmm.mlir
The reason for this is the SVE RUN lines use plain 'lli' rather than the
'%lli_host_or_aarch64_cmd' substitution that's necessary to run under
emulation. The CI doesn't support SVE so the tests will SIGILL unless
run under emulation.
I should note the logs don't show a SIGILL, only the non-descript:
FileCheck error: '<stdin>' is empty.
but I expect this is what's actually happening.

This patch addresses some of the flags and features that are currently
missing from the hermetic test support. This mostly just fixes the
`add_libc_test` option failing to find a few dependencies or missing
arguments from the previous unit test support.

For empty sections, RuntimeDyld always allocates 1 byte but leaves it
uninitialized. This causes the contents of some output sections to be

Assuming that the stack grows downwards, it is fine if the stack

For finding the last iteration of a loop, or the last section an
if condition is generated. Using scf::if can cause some lowering
issues since the code contained inside it can have branches. Using
fir::if instead ensures that the fir::if is lowered into branches
along with any code contained inside that can generate branches.

We just want to test whether the language switch works.
This is easier to control for libc++, since for bots building
the tests against libstdc++ we might not have the necessary
`<compare>` header available currently.
This patch resolves an issue where a value
is incorrectly displayed if it is represented
by DW_OP_div.
This issue is caused by lldb evaluating
operands of DW_OP_div as unsigned
and performed unintended unsigned
division.
This issue is resolved by creating two
temporary signed scalar and performing
signed division.
