A couple of passes that are parameterized in new-PM used different
pass names (in cmd line interface) while using the same pass class
name. This patch updates the PassRegistry to model pass parameters
more properly using PASS_WITH_PARAMS.
Reason for the change is to ensure that we have a 1-1 mapping
between class name and pass name (when disregarding the params).
With a 1-1 mapping it is more obvious which pass name to use in
options such as -debug-only, -print-after etc.
The opt -passes syntax is changed for the following passes:
early-cse-memssa => early-cse<memssa>
post-inline-ee-instrument => ee-instrument<post-inline>
loop-extract-single => loop-extract<single>
lower-matrix-intrinsics-minimal => lower-matrix-intrinsics<minimal>
This patch is not updating pass names in docs/Passes.rst. Not quite
sure what the status is for that document (e.g. when it comes to
listing pass paramters). It is only loop-extract-single that is
mentioned in Passes.rst today, out of the passes mentioned above.

basic_string and vector currently have a hard dependency on the compiled
library because they need to call __vector_base_common::__throw_xxx(),
which are externally instantiated in the compiled library. That makes
sense when exceptions are enabled (because we're trying to localize the
exception-throwing code to the compiled library), but it doesn't really
make sense when exceptions are disabled, and the __throw_xxx functions
are just calling abort() anyways.
This patch simply overrides the __throw_xxx() functions so that they
don't rely on the compiled library when exceptions are disabled.

The purpose of __attribute__((disable_sanitizer_instrumentation)) is to
prevent all kinds of sanitizer instrumentation applied to a certain
function, Objective-C method, or global variable.
The no_sanitize(...) attribute drops instrumentation checks, but may
still insert code preventing false positive reports. In some cases
though (e.g. when building Linux kernel with -fsanitize=kernel-memory
or -fsanitize=thread) the users may want to avoid any kind of
instrumentation.

The only thing that function should do as per it's semantic,
is to ensure that the switch's default is a block consisting only of
an `unreachable` terminator.
So let's just create such a block and update switch's default
to point to it. There should be no need for all this weird dance
around predecessors/successors.
This patch fixes an issue where RISCV's `findCommutedOpIndices` would
incorrectly return the pseudo `CommuteAnyOperandIndex` as a commutable
operand index, rather than fixing a specific index.

These changes don't come under OMPD guard as it is a movement of existing code to capture parallel behavior correctly.
"Runtime Entry Points for OMPD" like "ompd_bp_parallel_begin" and "ompd_bp_parallel_begin" should be placed at the correct execution point for the debugging tool to access proper handles/data.
Without the below changes, in certain cases, debugging tool will pick the wrong parallel and task handle.

This patch refactors the file generation API in Flang's frontend driver.
It improves the layering between `CreateDefaultOutputFile`,
`CreateOutputFile` (`CompilerInstance` methods) and their various
clients.
List of changes:
* Rename `CreateOutputFile` as `CreateOutputFileImpl` and make it
private. This method is an implementation detail.
* Instead of passing an `std::error_code` out parameter into
`CreateOutputFileImpl`, have it return Expected<>. This is a bit shorter
and more idiomatic LLVM.
* Make `CreateDefaultOutputFile` (which calls `CreateOutputFileImpl`)
issue an error when file creation fails. The error code from
`CreateOutputFileImpl` is used to generate a meaningful diagnostic
message.
* Remove error reporting from `PrintPreprocessedAction::ExecuteAction`.
This is only for cases when output file generation fails. This is
handled in `CreateDefaultOutputFile` instead (see the previous point).
* Inline `AddOutputFile` into its only caller,
`CreateDefaultOutputFile`.
* Switch from `lvm::buffer_ostream` to `llvm::buffer_unique_ostream>`
for non-seekable output streams. This simplifies the logic in the driver
and was introduced for this very reason in [1]
* Moke sure that the diagnostics from the prescanner when running `-E`
(`PrintPreprocessedAction::ExecuteAction`) are printed before the actual
output is generated.
* Update comments, add test.

Prevent SIFoldOperands from creating SALU instructions with a constant
and a frame index. Previously, only one operand was checked to be a
frame index, leading to too many constants when flat scratch is enabled

This patch allows target specific addr space in target builtins for HIP. It inserts implicit addr
space cast for non-generic pointer to generic pointer in general, and inserts implicit addr

It is NFC for non-HIP languages.

The rounding during type conversion uses multiple conversions, selecting
between them to try to discover if rounding occurred. This appears to
not have been tested, since it would generate code of the form:
float convert_float_rtp(char x)
{
float r = convert_float(x);
char y = convert_char(y);
[...]
}
which will access uninitialised data. The idea appears to have been to
have done a char -> float -> char roundtrip in order to discover the
rounding, so do this.
Discovered by inspection.

This prevents the async methods (which shoud be overridden by subclasses) from
hiding the blocking helper methods, avoiding a lot of 'using MemoryAccess::...'
boilerplate.
Accepts a vector of (SymbolStringPtr, ExecutorAddress*) pairs, looks up all the
symbols, then writes their address to each of the corresponding
ExecutorAddresses.
This idiom (looking up and recording addresses into a specific set of variables)
is used in MachOPlatform and the (temporarily reverted) ELFNixPlatform, and is
likely to be used in other places in the near future, so wrapping it in a
utility function should save us some boilerplate.
