[LLDB][formatters] Add formatter for libc++'s std::span

This patch adds a libcxx formatter for std::span. The
implementation is based on the libcxx formatter for
std::vector. The main difference is the fact that
std::span conditionally has a __size member based
on whether it has a static or dynamic extent.

Example output of formatted span:

(std::span<const int, 18446744073709551615>) $0 = size=6 {
  [0] = 0
  [1] = 1
  [2] = 2
  [3] = 3
  [4] = 4
  [5] = 5
}
The second template parameter here is actually std::dynamic_extent,
but the type declaration we get back from the TypeSystemClang is the
actual value (which in this case is (size_t)-1). This is consistent
with diagnostics from clang, which doesn't desugar this value either.
E.g.,:

span.cpp:30:31: error: implicit instantiation of undefined template
    'Undefined<std::span<int, 18446744073709551615>>'

FIR models Fortran intrinsic types with deliberate KIND values. Like
Fortran, COMPLEX and REAL have related KINDs in FIR. Lowering now
converts REAL types to floating point (MLIR) up front. This patch moves
the code to convert from FIR RealType to MLIR FloatType out of codegen

type returned as an MLIR FloatType.

We should consider whether to replace fir::ComplexType with
mlir::ComplexType at some point. I believe these types are presently

however.

Instead of trying to be clever and design our own locking primitive,
simply rely on the OS-provided implementation to do the right thing.

Indeed, manually yielding to the OS does not provide the necessary
information for it to make good prioritization decisions. For example,
if a thread with higher priority yields while waiting for a lock held
by a thread with lower priority but the system is contended, it is
possible for the thread with lower priority to not run until the higher
priority thread has yielded 16 times and goes for __libcpp_mutex_lock().
Once that happens, the OS can bump the priority of the thread that
currently holds the lock to unblock everyone. So instead, we might as
well give the system all the information from the start so it can make
appropriate decisions.

As a fly-by change, also increase the number of locks in the table.

[Clang] Change host/device only compilation to a driver mode

We use the flags `--offload-host-only` and `--offload-device-only` to
change the driver's code generation for offloading programs. These are
currently parsed out independently in many places. This patch simply
refactors this to work as a mode for the Driver. This stopped us from

`; CHECK: ret`. That's for consistency with other tests that generate
assembly. We could change that if that's what folks prefer.
