Andrzej Warzynski c3ebb53eab [flang][unittest] Add a missing dependency
In https://reviews.llvm.org/D103612, a definition of an instance of
`Fortran::parser::AnalyzedObjectsAsFortran` was moved (that object is
used in unparsing). That, in turn, introduced a dependency of the unit
tests on the `FortranEvaluate` library, which defines
`AnalyzedObjectsAsFortran`.

That dependency was missed in D103612 and has caused shared-library
builds to fail. I'm submitting this without a review, as it's rather
straightforward omission.

Change the reshape flang unit test to use the new interface. Also, add an
order argument to exercise the order subscript code in the rehsape runtime

Diana Picus 4498137bd7 [flang] Rewrite test for CPU_TIME
Don't rely on volatile writes to keep the CPU busy - it seems MSVC
optimizes them out, so we don't get different values for 'start' and
'end' on Windows. Rewrite the test to loop until we get a different
value for 'end'.

peter klausler 8ba9ee46e4 [flang] Correct the subscripts used for arguments to character intrinsics
When chasing down another unrelated bug, I noticed that the
implementations of various character intrinsic functions assume
that the lower bounds of (some of) their arguments were 1.
This isn't necessarily the case, so I've cleaned them up, tweaked
the unit tests to exercise the fix, and regularized the allocation
pattern used for results to use SetBounds() before Allocate() rather
than the old original Descriptor::Allocate() wrapper around
CFI_allocate().

Since there were few other remaining uses of the old original
Descriptor::Allocate() wrapper, I also converted them to the
new one and deleted the old one.

Diana Picus 45cd405dc0 [flang] Add clang-tidy check for braces around if
Flang diverges from the llvm coding style in that it requires braces
around the bodies of if/while/etc statements, even when the body is
a single statement.

This commit adds the readability-braces-around-statements check to
flang's clang-tidy config file. Hopefully the premerge bots will pick it
up and report violations in Phabricator.

We also explicitly disable the check in the directories corresponding to
the Lower and Optimizer libraries, which rely heavily on mlir and llvm
and therefore follow their coding style. Likewise for the tools
directory.

We also fix any outstanding violations in the runtime and in
lib/Semantics.

Define APIs, naively implement, and add basic sanity unit tests for
the transformational intrinsic functions CSHIFT, EOSHIFT, PACK,
SPREAD, TRANSPOSE, and UNPACK.  These are the remaining transformational

in place as a stress test for the runtime's descriptor handling
facilities.

Code is in place to create copies of allocatable/automatic
components when transforming arrays of derived type, but it won't
do anything until we have derived type information being passed to the
runtime from the frontend.

Diana Picus aaab70407b [flang] Fix handling of elem_len in CFI_establish
The current code computes the minimum element length based on the `type`
used to create the descriptor and uses that as the element length
whenever it is greater than 0. This means that the `elem_len` parameter
is essentially ignored for any type where we can compute a minimum
element length (which includes `CFI_type_char[16|32]_t`), and we may
therefore end up with descriptors with a lower element length than
expected.

This patch fixes the issue by explicitly doing what the standard says,
i.e. it uses the given `elem_len` for character types, `CFI_type_struct`
and `CFI_type_other`, and ignores it (falls back to the minimum element
length) for everything else.

added, making that assumption no longer true. Luckily, in the meantime
we also got a define for CFI_TYPE_LAST, which we can now use to allow
CFI_establish and CFI_allocate to work with descriptors of
CFI_type_char16_t, CFI_type_char32_t and any other future types.

* Usage of "long double" in the compiler was cleaned up a
  bit, and host dependences on x86 / MSVC have been isolated
  in a new Common/long-double header.
* Character comparison has been exposed via an extern template
  so that reductions could use it.
* Mappings from Fortran type category/kind to host C++ types
  and vice versa have been isolated into runtime/cpp-type.h and
  then used throughout the runtime as appropriate.
* The portable 128-bit integer package in Common/uint128.h

Add a reference to the singleton SemanticsContext to each Scope.

All of this allows operator< to be implemented on Symbols by
