b90ebbc5bd [flang] Fold the RHS of assignment
In order to emit overflow warnings from assignment statements whose
right-hand sides are constants that undergo conversions, run the
right-hand sides of assignments through constant folding after the
conversions have been made explicit in expression analysis.

4cc9437a7e [flang] Set default to -ffpcontract=fast
Following RFC at
https://discourse.llvm.org/t/rfc-ffp-contract-default-value/66301

This adds the `fastmath<contract>` attribute to `fir.call` and some
floating point arithmetic operations (hence the many test changes).
Instead of testing for this specific attribute, I am using a regular
expression to match any attributes.

13f9089ac9 [flang] Fix one corner case in reshape intrinsic
As Fortran 2018 16.9.163, the reshape is the only intrinsic which
requires the shape argument to be rank-one integer array and the SIZE
of it to be one constant expression. The current expression lowering
converts the shape expression with slice in intrinsic into one box value
with the box element type of unknown extent. However, the genReshape
requires the box element type to be constant size. So, convert the box
value into one with box element type of sequence of 1 x constant. This
corner case is found in cam4 in SPEC 2017
https://github.com/llvm/llvm-project/issues/56140.

[flang][NFC] Add array lowering tests
These tests were left behind during the upstreaming of parts lowering.

This patch is part of the upstreaming effort from fir-dev branch.
