[flang] Runs FIR SimplifyRegionLitePass pass after calling the inliner

In flang pipeline, the inliner calls createCanonicalizerPass with the region
simplification disabled. The inliner pass does canonicalization even if
no inlining happens. After canonicalization, FIR lite region simplification
must be called to get rid of unreachable regions.
This code exposes the need to run SimplifyRegionLitePass after the inliner is
called with FIR pipeline.

[flang] Run algebraic simplification optimization pass.

Try 2 to merge 4fbd1d6c872e8228f23a6e13914222af40ca6461.

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.

[flang][nfc] Add missing `REQUIRES: asserts` in tests

Tests that use `--mlir-pass-statistics-display=` from MLIR require the
following condition to hold: (extracted from LLVM's Statistics.h):
```
#define LLVM_ENABLE_STATS 1
```
This is normally enforced with `REQUIRES: asserts`. This patch updates
relevant Flang tests accordingly.

For "Release" builds (with assertions disabled), the affected tests will
be failing without this change.

[Flang] Call the CSE pass in the pass pipeline

During the upstreaming process, it was decided to move contents
of the FIR CSE pass to the MLIR pass. Most of the FIR CSE changes
that are used are already moved to the MLIR pass. This patch calls
the MLIR CSE pass in places where the FIR CSE pass is called in the
pass pipeline.

Note: This is part of upstreaming from the fir-dev branch of
https://github.com/flang-compiler/f18-llvm-project.

This was leftover from when the standard dialect was destroyed, and
when FuncOp moved to the func dialect. Now that these transitions
have settled a bit we can drop these.

Most updates were handled using a simple regex: replace `^( *)func` with `$1func.func`

[flang] Add ExternalNameConversionPass to pass pipeline

This seems to be the consensus in
https://github.com/flang-compiler/f18-llvm-project/issues/1316

The patch adds ExternalNameConversion to the default FIR CodeGen pass
pipeline, right before the FIRtoLLVM pass. It also adds a flag to
optionally disable it, and sets it in `tco`. In other words, `flang-new`
and `flang-new -fc1` will both run the pass by default, whereas `tco`
will not, so none of the tests need to be updated.

This patch adds Win32 to the list of supported triples in

triple, even when running tests on Windows. Currently this affects only
1 test, but it will change once we start adding more tests for lowering
and code-generation.
