Avoid doing the following combine for vector types:
```
copysign(x, fp_extend(y)) -> copysign(x, y)
copysign(x, fp_round(y)) -> copysign(x, y)
```
That combine seemed to impede the selection of vector instruction and cause
a mess in some circumstances.

Not all platforms accept -stdlib or -rtlib. Instead of complaining about
the wrong argument to these options, clang complains about the option
itself being present.
Pass an appropriate -target to the clang invocations.
Allow assembler expressions to start with an identifier. This allows for expressions such as
```
b symbol + 4
```
and
```
mov symEnd - symStart, %g1
```

Some Windows build bots report `FileSystemOpts` and `MigratorOpts` as undeclared. This fix renames the parameter and declares a local variable with the original name.
This patch splits out the last two option groups (`Filesystem` and `Migrator`) into their own `Parse`/`Generate` functions.
This effectively removes the need for `parseSimpleArgs` and marshalling block in `CompilerInvocation::generateCC1CommandLine`.
The two new `Parse`/`Generate` functions are not part of the round-trip, because they contain no custom code and the very next patch starts round-tripping the whole `CompilerInvocation`.

MLIRContext allows its users to access directly to the DialectRegistry it
contains. While sometimes useful for registering additional dialects on an
already existing context, this breaks the encapsulation by essentially giving
raw accesses to a part of the context's internal state. Remove this mutable
access and instead provide a method to append a given DialectRegistry to the
one already contained in the context. Also provide a shortcut mechanism to
construct a context from an already existing registry, which seems to be a
common use case in the wild. Keep read-only access to the registry contained in
the context in case it needs to be copied or used for constructing another
context.
With this change, DialectRegistry is no longer concerned with loading the
dialects and deciding whether to invoke delayed interface registration. Loading
is concentrated in the MLIRContext, and the functionality of the registry
better reflects its name.

This introduces a mechanism to register interfaces for a dialect without making
the dialect itself depend on the interface. The registration request happens on
DialectRegistry and, if the dialect has not been loaded yet, the actual
registration is delayed until the dialect is loaded. It requires
DialectRegistry to become aware of the context that contains it and the context
to expose methods for querying if a dialect is loaded.
This mechanism will enable a simple extension mechanism for dialects that can
have interfaces defined outside of the dialect code. It is particularly helpful
for, e.g., translation to LLVM IR where we don't want the dialect itself to
depend on LLVM IR libraries.

This patch optimizes a build_vector "index sequence" and lowers it to
the existing custom RISCVISD::VID node. This pattern is common in
autovectorized code.
The custom node was updated to allow it to be used by both scalable and
fixed-length vectors, thus avoiding pattern duplication.

Update OpenMP and OpenACC semantics tests to use the new driver if it is built, otherwise use f18.
OpenMP tests that include `use omp_lib` or run `test_symbols.sh` have not been updated as they require options `-intrinsic-module-directory` and `-funparse-with-symbols` which are currently not implemented in the new driver.
Similarly OpenACC tests that run `test_symbols.sh` have not been updated.
This patch also moves semanticsContext to CompilerInvocation and creates it in CompilerInvocation#setSemanticsOpts so that the semantics context can use Fortran::parser::Options#features.
Summary of changes:
- Move semanticsContext to CompilerInvocation.h
- Update OpenMP and OpenACC semantics tests that do not rely on `-intrinsic-module-directory` and `-funparse-with-symbols` to use %flang

This patch is a preparatory patch with the ultimate goal of making

This finalizes the patch serious to make Polly run in the default
configuration when using the NewPM by default.
In particular, print the ast with -debug-only=polly-ast, print a

-polly-code-generation=ast.
TargetTransformInfo is required by IslScheduleOptimizer, as ScopPass.
Unfortunately it is not possible to get arbitrary larger-unit analyses
in for as ScopPass. Loop passes also already use TargetTransformInfo as
LoopStandardAnalysisResults, hence wei might expect it to be available
to Scop passes as well.
The pass-instrumentation pass is implicitly execute by the NewPM
whenever a new analysis runs. Not registering it will cause the crash
whenever a scop pass requests an analysis.
For instance this is the case for the IstAstAnalysis requesting the
DependenceAnalsis result.

Since ToolChain::GetCXXStdlibType() is a simple getter that might emit
the "invalid library name in argument" warning, it can conceivably be
called several times while initializing the build pipeline.
Before this patch, a simple 'clang++ -stdlib=foo ./test.cpp' would print
the warning twice, -rt=lib=foo would print 6 times.
Change this and always only print the warning once. Keep the rest of the
