[flang] Fix problems with constant arrays with lower bounds that are not 1

There were two problems with constant arrays whose lower bound is not 1.
First, when folding the arrays, we were creating the folded array to have lower
bounds of 1 but, we were not re-adjusting their lower bounds to the
declared values.  Second, we were not calculating the extents correctly.
Both of these problems led to bogus error messages.

I fixed the first problem by adjusting the lower bounds in
NonPointerInitializationExpr() in Evaluate/check-expression.cpp.  I wrote the
class ArrayConstantBoundChanger, which is similar to the existing class
ScalarConstantExpander.  In the process of implementing and testing it, I found
a bug that I fixed in ScalarConstantExpander which caused it to infinitely
recurse on parenthesized expressions.  I also removed the unrelated class
ScalarExpansionVisitor, which was not used.

I fixed the second problem by changing the formula that calculates upper bounds
in in the function ComputeUpperBound() in Evaluate/shape.cpp.

I added tests that trigger the bogus error messages mentioned above along with
a constant folding tests that uses array operands with shapes that conform but
have different bounds.

In the process of adding tests, I discovered that tests in
Evaluate/folding09.f90 and folding16.f90 were written incorrectly, and I
fixed them.  This also revealed a bug in contant folding of the
intrinsic "lbounds" which I plan to fix in a later change.

[GlobalISel] Fix modifying a G_OR without notifying the observer

Remove the call to setFlags in favour of creating the instruction with
the correct flags in the first place, so we don't have to explicitly
notify the observer.

[AArch64][Clang][Linux] Enable out-of-line atomics by default.

Generate outline atomics if compiling for armv8-a non-LSE AArch64 Linux
(including Android) targets to use LSE instructions, if they are available,
at runtime. Library support is checked by clang driver which doesn't enable
outline atomics if no proper libraries (libgcc >= 9.3.1 or compiler-rt) found.

[OpenMP] Add environment variable to force monotonic dynamic scheduling

This patch introduces a new environment variable to force monotonic
behavior for users that absolutely need it.  This is in anticipation
of 5.0 change that uses non-monotonic behavior for dynamic scheduling
by default. Fixes for that and the actual switch are coming soon.

[SPEC2017] Use inputs from RUN directory.

At the moment, some benchmarks use inputs from the INPUT/SRC directory.
Those are not copied to the device, if one is specified. To ensure the
input is available on device, use it from the RUN_* directories and use
speccpu2017_prepare_rundir to copy them to the run directory. This will
automatically copy them to the specified device as well.
