  [libc] Add dlinfo + RTLD_DI_* macros to dlfcn.h (#149938)

An initial commit for #149911, this adds a stub implementation for
dlinfo and the enums list of `RTLD_DI_*` values.

While the dlinfo implementation relies on dynamic linker support, this
patch will add its prototype in the generated dlfcn.h header so that it
can be used by downstream platforms that have their own dlinfo
implementation.

  [flang][runtime] Fix child input bugs under NAMELIST (#151571)

When NAMELIST input takes place on a derived type, we need to preserve
the type in the descriptor that is created for storage sequence
association. Further, the fact that any child list input in within the
context of a NAMELIST must be inherited so that input fields don't try
to consume later "variable=" strings.

Fixes https://github.com/llvm/llvm-project/issues/151222.

  [flang][runtime] Don't always accept a bare exponent letter (#151597)

For more accurate compatibility with other compilers' extensions, accept
a bare exponent letter as valid real input to a formatted READ statement
only in a fixed-width input field. So it works with (G1.0) editing, but
not (G)/(D)/(E)/(F) or list-directed input.

Fixes https://github.com/llvm/llvm-project/issues/151465.

   [flang][runtime] Optimize Descriptor::FixedStride() (#151755)

Put the common cases on fast paths, and don't depend on IsContiguous()
in the general case path. Add a unit test, too.

  [flang][runtime] Handle empty NAMELIST value list (#151770)

InputNamelist() returns early if any value list read in by
InputDerivedType() or DescriptorIo<Input>() is empty, since they return
false. But an empty value list is okay, and the early return should
occur only on error.

Fixes https://github.com/llvm/llvm-project/issues/151756.

  [flang] Minor speed-up to module file parsing (#152178)

Module files shouldn't ever produce parsing errors, and if they did in
the case of a badly-generated module file, the compiler will notice and
crash. So we can run the parser on module files with message deferral
enabled, and that saves time that would otherwise be spent generating
messages on failed parsing alternatives that are discarded anyway when
backtracking. It's not a big savings (single digit percentage on overall
compilation time for a big application with lots of modules), but worth
doing.
