Fortran provide types whose values may be dynamically allocated
or associated with a variable under explicit program control.
The purpose of this commit is:
* to read allocated/associated DWARF tags and store them in
the dynamic property list of main_type.
* enable GDB to print the value of a dynamic array in Fortran
in case the type is allocated or associated (pointer to
dynamic array).
Examples:
(gdb) p vla_not_allocated
$1 = <not allocated>
(gdb) p vla_allocated
$1 = (1, 2, 3)
(gdb) p vla_ptr_not_associated
$1 = <not associated>
(gdb) p vla_ptr_associated
$1 = (1, 2, 3)
Add basic test coverage for most dynamic array use-cases in Fortran.
The commit contains the following tests:
* Ensure that values of Fortran dynamic arrays
can be evaluated correctly in various ways and states.
* Ensure that Fortran primitives can be evaluated
correctly when used as a dynamic array.
* Dynamic arrays passed to subroutines and handled
in different ways inside the routine.
* Ensure that the ptype of dynamic arrays in
Fortran can be printed in GDB correctly.
* Ensure that dynamic arrays in different states
(allocated/associated) can be evaluated.
* Dynamic arrays passed to functions and returned from
functions.
* History values of dynamic arrays can be accessed and
printed again with the correct values.
* Dynamic array evaluations using MI protocol.
* Sizeof output of dynamic arrays in various states.
The patch was tested using the test suite on Ubuntu 12.04 64bit.

This fixes two FAIL results on this testcase which were caused by a
misplaced "continue" command. This testcase used to end inferior's
execution too soon, causing the following tests to fail. Now we break
right after inferior's loop and perform the rest of the tests there.
gdb/testsuite/ChangeLog:
* gdb.fortran/array-element.exp: Remove unexpected "continue"
command in testcase. Simplify testcase.
This commit fixes the PR mentioned in $subject. It is about a set but
unused variable that refers to the output format of integer values
printed in Fortran.
This was probably a thinko (like most set-but-unused-vars), but it
could cause an internal error depending on the scenario. I am sending
a testcase which triggers this error as well.

Added new domain MODULE_DOMAIN for fortran modules to avoid
issues with sharing namespaces (e.g. when a variable currently
in scope has the same name as a module).
(gdb) ptype modname
old> No symbol "modname" in current context.
new> type = module modname
This fixes PR 15209 and also addresses the issue
with sharing namespaces:
