Peter Klausler e9d0f8baf2 [flang] Don't drop format string for external child I/O
In user-defined derived type I/O to an external unit, don't
omit the format string from the constructor of ChildFormattedIoStatement.
And include any user IOMSG text in the crash message of the
parent, if it doesn't catch errors.

Peter Klausler 3726626a26 [flang] Fix crash from USE-associated defined I/O subprograms
User-defined derived type I/O implementation subroutines and
generic interfaces may be USE-associated, but the code that builds
the type description table wasn't allowing for that possibility.
Add a call to GetUltimate() to cope.

Peter Klausler 04eb93b1d5 [flang] Fix repeated "DT" editing
User-defined derived type editing in formatted I/O wasn't
working with repeat counts; e.g., "2DT(10)".  The solution required
some code to be moved from GetNextDataEdit() to CueUpNextDataEdit() so
that a stack entry for a nonparenthesized repeated data edit
descriptor would work correctly -- all other data edit descriptors
are capable of dealing with repetition in their callees, so the bug
hadn't been exposed before.

Debugging this problem led to some improvements in error messages
for bad format strings, and those changes have been retained; also,
a dead member function was discovered and expunged.

[flang] Update tco tool pipline and add translation to LLVM IR
tco is a tool to test the FIR to LLVM IR pipeline of the Flang compiler.

This patch update tco pipelines and adds the translation to LLVM IR.

A simple test is added to make sure the tool is working with a simple
FIR program.
More tests will be upstream in follow up patch from the fir-dev branch.

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

John Ericson df31ff1b29 [cmake] Make include(GNUInstallDirs) always below project(..)
Its defaulting logic must go after `project(..)` to work correctly,  but `project(..)` is often in a standalone condition making this
awkward, since the rest of the condition code may also need GNUInstallDirs.

The good thing is there are the various standalone booleans, which I had missed before. This makes splitting the conditional blocks less awkward.

Jean Perier 81c6693329 [flang] Prevent any non constant result extent to be inlined on caller side
UBOUND, SIZE, and SHAPE folding was still creating expressions that are
invalid on the caller side without the call expression context.
A previous patch intended to deal with this situation (https://reviews.llvm.org/D116933)
but it assumed the return expression would be a descriptor inquiry to
the result symbol, which is not the case if the extent expression is
"scope invariant" inside the called subroutine (e.g., referring to
intent(in) dummy arguments). Simply prevent folding from inlining non
constant extent expression on the caller side.

Folding could be later improved by having ad-hoc folding for UBOUND, SIZE, and
SHAPE on function references where it could try replacing the dummy symbols
by the actual expression, but this is left as a possible later improvement.
