[libc++][chrono] Fixes month inc and dec operations.
The operator++, operator++(int), operator--, and operator--(int) need to
change the month to a valid value. The wording is specified in terms of
operator+(const month& x, const months& y) noexcept;
which has the correct behavior. The aforementioned operators instead
used ++/-- on the internal value direction, resulting in incorrect
behaviour.
As a drive-by improve the unit tests:
- use the typical constexpr test method
- test whether the month is valid after the operations
- format the tests

[openacc] Add dialect definition for acc declare
A declare directive is used to specify the creation of a visible device
copy of a variable for the duration of the implicit data region as it
relates to the scope in which the variable is declared.
In order to support this, the following new operations were added:
1) `acc.global_ctor` and `acc.global_dtor`. These are used whenever the
declare directive applies to a global.
2) `acc.declare_enter` and `acc.declare_exit`. These operations are
modeled similarly to `acc.enter_data` and `acc.exit_data`. The reason
they are not modeled like `acc.data` is so that these operations can be
used both for globals and regions like functions.
3) `acc.declare_device_resident` and `acc.declare_link`. These
operations are modeled in a manner consistent with previously defined
data entry operation model.
The `acc.getdeviceptr` was generalized so that it can be used with
acc.declare_exit.

[mlir][LLVM] Append call ops alias scopes to inlined operations
Currently when inlining, any alias scope information previously attached to the call op is lost. This leads to a loss of information that could be used by alias analysis to determine that two memory access operations do not alias.

[mlir][LLVM] Perform deep clone of alias scopes during inlining
This is the first and most basic and important step for inlining memory operations with alias scopes.
For correctness, it is required that any alias scopes of inlined operations are replaced with deep copies. This is necessary as otherwise the same function could be inlined twice in one function, and suddenly the alias scopes extended.
A simple example would be `foo(a, b); foo(a2, b2)`. `a` and `a2` may alias. If `foo` is inlined in both instances, the store and load operations from `foo` may suddenly claim that `a` and `a2` do not alias if we were to keep the original alias scopes.

[flang][hlfir] support dynamically optional array arguments to intrinsics with custom handling
The previous code path created the elemental kernel by generating a
scalar intrinsic call using pre-prepared arguments using genIntrinsicRefCore,
which then generated the intrinsic call using genIntrinsicCall().
The problem with this approach was that the dynamically optional
arguments were marked as having no argLowering, which meant that they
were unconditionally passed by value without any check to see if they
were present.
It would be nice to put an if operation in the path for !argLowering,
doing something similar to genOptionalValue(). However, this can't be
done because it isn't clear what value should be used for the default.
If zero was used (like in genOptionalValue) this could effect the result
of MIN or MAX.
Instead, this patch re-uses the implementation for scalar dynamically
optional arguments (in non-elemental calls). This does the correct
thing, entirely ignoring absent optional arguments.
