gdb/ChangeLog:

        error message.

[Ada] Make the exception_support_info data per inferior.

The ada-lang module was using a static global called "exception_info"
for all inferiors.  But each inferior might be different, and thus
this patch makes this data per-inferior.

gdb/ChangeLog:

        * ada-lang.c (struct ada_inferior_data) [exception_info]:
        New field.
        (exception_info): Delete.

Warn if missing debug info for Ada exception catchpoints

This patch should help the user understand why the debugger is not
able to insert Ada exception catchpoints when the Ada runtime was
stripped of debugging info, as is often the case on many GNU/Linux
distros:

    (gdb) catch exception
    Your Ada runtime appears to be missing some debugging information.
    Cannot insert Ada exception catchpoint in this configuration.

gdb/ChangeLog:

        * ada-lang.c (ada_has_this_exception_support): Raise an error
        if we could find the Ada exception hook in the Ada runtime,
        but no debugging info for that hook.

gdb/testsuite/ChangeLog:

        * gdb.ada/catch_ex.exp, gdb.ada/mi_catch_ex.exp: Adjust
        expected output for unsupported case.

Ada exception catchpoint support cleanup.

This patch cleans up a bit the way we detect which type of runtime
the program uses with respect to Ada exceptions. It also removes
an unnecessary check in ada_exception_sal which is already performed
by ada_exception_support_info_sniffer.

Some of the changes are preparation work for detecting the situation
where the Ada runtime is found, but lacking debugging info.

gdb/ChangeLog:

        * ada-lang.c (ada_has_this_exception_support): New function,
        extracted out of ada_exception_sal and ada_exception_sal.
        (ada_exception_support_info_sniffer): Simplify by using
        ada_has_this_exception_support.
        (ada_exception_sal): Replace unnecessary checks by assertions.
        Minor simplifications.

fix incorrect assumption in gdb.ada/watch_arg

The testcase is assuming that the parameter being watched isn't being
modified. But the way the test program is written, this is not true
at all.  So this changes fixes the code to still reference the variable,
but in a way that does not modify its value.

gdb/testsuite:

        * gdb.ada/watch_arg/pck.ads, gdb.ada/watch_arg/pck.adb: New files.
        * gdb.ada/watch_arg/watch.adb: Adjust code to avoid modification
        of parameter X in procedure Foo.
