Preliminary work on HLFIR. Introduce option that will allow testing
lowering via HLFIR until this is ready to replace the current expression
lowering.
See https://reviews.llvm.org/D134285 for more context about the plan.

To accomplish this, this patch creates an optional list of environment
variable default values to be set by the runtime to allow directly using
the existing runtime implementation of FORT_CONVERT for I/O conversions.
It is useful for couple of test suite like NAG to keep failing
with a TODO until the polymorphic entities is implemented all the
way done to codegen.
This pass adds a flag to LoweringOptions for experimental development.
This flag is off by default and can be enable in `bbc` with `-polymorphic-type`.
Options can be added in the driver and tco when needed.

The real(10) is supported on x86_64. On aarch64, the value of
selected_real_kind(16) should be 16 rather than 10 since real(10)
is not supported on x86_64. Previously, the real type support check
is not target dependent. Support it now through the target triple
information.

This commit addresses concerns raised in D129497.
Propagate lowering options from driver to expressions lowering
via AbstractConverter instance. A single use case so far is
using optimized TRANSPOSE lowering with O1/O2/O3.
bbc does not support optimization level switches, so it uses
default LoweringOptions (e.g. optimized TRANSPOSE lowering
is enabled by default, but an engineering -opt-transpose=false
option can still override this).

The options -f{no-}color-diagnostics have been supported in driver. This
supports the behaviors in scanning, parsing, and semantics, and the
behaviors are exactly the same as the driver.
To illustrate the added behaviour, consider the following input file:
```! file.f90
program m
integer :: i = k
end
```
In the following invocations, "error: Must be a constant value" _will be_
formatted:
```
$ flang-new file.f90
error: Semantic errors in file.f90
./file.f90:2:18: error: Must be a constant value
integer :: i = k
```
Note that "error: Semantic errors in file.f90" is also formatted, which
is supported in https://reviews.llvm.org/D126164.
Also note that only "error", "warning" and "portability" are formatted.
Check the following input file:
```! file2.f90
program m
integer :: i =
end
```
```
$ flang-new test2.f90
error: Could not parse test2.f90
./test2.f90:2:11: error: expected '('
integer :: i =
^
./test2.f90:2:3: in the context: statement function definition
integer :: i =
^
...
```
The "error: Could not parse test2.f90" and "error: expected '('" are
formatted. Others such as "in the context" are not formatted yet, which
may or may not be supported.

Flang algebraic simplification pass will run algebraic simplification
rewrite patterns for Math/Complex/etc. dialects. It is enabled
under opt-for-speed optimization levels (i.e. for O1/O2/O3; Os/Oz will not
enable it).
With this change the FIR/MLIR optimization pipeline becomes affected
by the -O* optimization level switches. Until now these switches
only affected the middle-end and back-end.

Create a TargetCharacteristics class to centralize the few items of
target specific information that are relevant to semantics. Use the
new class for all target queries, including derived type component layout
modeling.
Future work will initialize this class with target information
provided or forwarded by the drivers, and use it to fold layout-dependent
intrinsic functions like TRANSFER().

rework a piece of code, to dodge warnings on flag from
GCC 11 build bots exposed by a recent patch.
Applying without review to get bots working again; changes
also tested against GCC 9.3.0.
This patch enable lowering from Fortran to FIR for a basic empty
program. It brings all the infrastructure needed for that. As discussed
previously, this is the first patch for lowering and follow up patches
should be smaller.
With this patch we can lower the following code:
```
program basic
end program
```
To a the FIR equivalent:
```
func @_QQmain() {
return
}
```
Follow up patch will add lowering of more complex constructs.
