bfd0703234 [flang] Fix test script portability problems. 
Allow for bash anywhere on path.

Allow for utilites to be in /bin as well as /usr/bin.

Don't count on sed understanding '\t'.

The options to mktemp aren't portable. Instead just create a per-test
temp directory in the working directory (i.e. <build-dir>/test/semantics).
Setting the KEEP environment variable causes them all to be kept to help
in investigating failures.

Fixes flang-compiler/f18#128.

0c575ed548 [flang] Implement writing of .mod files. 
Module file writing is implemented in mod-file.cc. They need to be
written after all semantic checking. Until then, for testing, write
them out whenever names are resolved.

There is a header comment in the .mod files but it is mostly a
placeholder until we can read them in and do something with it.

Rename `Symbol::details<D>` to `Symbol::get<D>`. This asserts that the
details of the symbol match D and returns that type. But we need a way
to access the details as a variant as well (not just one of its types).
`details()` is the best name for that, especially as we already have
`set_details()`. Renaming the old `details` to `get` also better matches
`has` which is used to check which variant is present.

d42bb955a6 [flang] Support intent-stmt and resolve subprogram prefixes and suffixes. 
Recognize `IntentStmt` and use `HandleAttributeStmt()` to implement it
as is done with other attribute statements. Add `Attr::INTENT_INOUT` as
a separate attribute for `INTENT(INOUT)`.

Collect attributes from the prefix and suffix of `FunctionStmt` and
`SubroutineStmt` (including `BIND(C)`) and set them on the subprogram
symbol.

Create a test for this using `test_symbol.sh`. It compiles with
`-funparse-with-symbols` and compares the output with the symbols in
comments in the input.

Change `test_errors.sh` to be similar to `test_symbol.sh`: check usage
and allow `F18` environment variable to override the path to the
compiler.

d7d69474c8 [flang] Fix bug recognizing derived type constructor call 
A ProcedureDesignator is a derived type constructor call if the name
resolves to a derived type. We need to recognize it as such and not
report an error. It may be in another derived type so we have to call
FindSymbol() first to find the derived type.

Most of the diffs are due to `symbol` changing from a reference to a
pointer.

In this example we were reporting an error on the first `t1()` and
resolving the second as an external function call.
```
module m
  type :: t1
  end type
  type(t1) :: x = t1()
  type t2
    type(t1) :: y = t1()
  end type
end module
```
