Tim Keith 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.

Tim Keith 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.

Tim Keith 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.
