[SelectionDAG] Remove an early-out from computeKnownBits for smin/smax

Even if we know nothing about LHS, it can still be useful to know that
smax(LHS, RHS) >= RHS and smin(LHS, RHS) <= RHS.

[LLDB] MinidumpParser: Prefer executable module even at higher address

When a program maps one of its own modules for reading, and then
crashes, breakpad can emit two entries for that module in the
ModuleList.  We have logic to identify this case by checking permissions
on mapped memory regions and report just the module with an executable
region.  As currently written, though, the check is asymmetric -- the
entry with the executable region must be the second one encountered for
the preference to kick in.

This change makes the logic symmetric, so that the first-encountered
module will similarly be preferred if it has an executable region but
the second-encountered module does not.  This happens for example when
the module in question is the executable itself, which breakpad likes to
report first -- we need to ignore the other entry for that module when
we see it later, even though it may be mapped at a lower virtual
address.

[HIP] Add signbit(long double) decl

An _MSC_VER version of signbit(long double) is required for MSVC headers.

Support emptiness checks for unbounded FlatAffineConstraints.

With this, we have complete support for emptiness checks. This also paves the way for future support to check if two FlatAffineConstraints are equal.

[OpenMP] Drop the static library libomptarget-nvptx

For NVPTX target, OpenMP provides a static library `libomptarget-nvptx`
built by NVCC, and another bitcode `libomptarget-nvptx-sm_{$sm}.bc` generated by
Clang. When compiling an OpenMP program, the `.bc` file will be fed to `clang`
in the second run on the program that compiles the target part. Then the generated
PTX file will be fed to `ptxas` to generate the object file, and finally the driver
invokes `nvlink` to generate the binary, where the static library will be appened
to `nvlink`.

One question is, why do we need two libraries? The only difference is, the static
library contains `omp_data.cu` and the bitcode library doesn't. It's unclear why
they were implemented in this way, but per D94565, there is no issue if we also
include the file into the bitcode library. Therefore, we can safely drop the
static library.

This patch is about the change in OpenMP. The driver will be updated as well if
this patch is accepted.
