also filter label symbols

The bug here is that, with dwz -m, a function (and a label) appear in
both a PU and a CU when running cplabel.exp.  So, a breakpoint gets
two locations:

    (gdb) break foo::bar:to_the_top
    Breakpoint 2 at 0x400503: foo::bar:to_the_top. (2 locations)

What is especially wacky is that both locations are at the same place:

    (gdb) info b
    Num     Type           Disp Enb Address            What
    1       breakpoint     keep y   <MULTIPLE>
    1.1                         y     0x000000000040051c foo::bar:get_out_of_here
    1.2                         y     0x000000000040051c foo::bar:get_out_of_here

This happens due to the weird way we run "dwz -m".
It's unclear to me that this would ever happen for real code.

While I think this borders on "diminishing returns" territory, the fix
is pretty straightforward: use the existing address-filtering function
in linespec to also filter when looking at labels.

Built and regtested (both ways) on x86-64 Fedora 18.

	* linespec.c (convert_linespec_to_sals): Use maybe_add_address
	when adding label symbols.
fix recursively_compute_inclusions and add dwz test case

Doug pointed out a while ago that in the final dwz -m patch, nothing
ever set symtab::user.

This patch fixes this oversight and adds a test case showing why it is
important.

Built and regtested (both ways) on x86-64 Fedora 18.
The new test unconditionally tests the partial unit machinery, which I
think is an added plus.

	* dwarf2read.c (recursively_compute_inclusions): Add
	"immediate_parent" argument.  Set symtab's "user" field
	if not set.
	(compute_symtab_includes): Update.

	* gdb.dwarf2/dwz.exp: New file.
use language of the main symbol

With "dwz -m", "main" appears in both the PU and the importing CU when
running anon-struct.exp.  However, the PU does not have a file name.
So, find_main_filename returns the empty string, making
deduce_language_from_filename return language_unknown.

This patch fixes this problem by changing gdb to use the ordinary
symbol-lookup functions to find "main"'s symbol.  Then, it examines the
symbol's language.

I think this is cleaner than the current approach.  For one thing it
avoids trying to guess the language based on the source file name,
instead deferring to the presumably more reliable debuginfo.

Another possible fix would have been to change how the file name is
found via the "qf" methods.  However, I think the approach given is
preferable for the reason outlined above.

This required a minor test suite change, as now a symtab is expanded
during the search for "main".

Built and regtested (both ways) on x86-64 Fedora 18.

	* symfile.c (set_initial_language): Look up "main" symbol
	and use its language.
	* symtab.c (find_main_filename): Remove.
	* symtab.h (find_main_filename): Remove.

	* gdb.base/maint.exp: Allow zero symtabs to be expanded.
remove unused qf method

After the previous patch in the series, nothing uses the "quick"
method find_symbol_file.

This patch removes it.

Tested by rebuilding.

	* dwarf2read.c (dw2_get_primary_filename_reader): Remove.
	(dwarf2_gdb_index_functions): Update.
	* psymtab.c (find_symbol_file_from_partial): Remove.
	(psym_functions): Update.
	* symfile.h (struct quick_symbol_functions) <find_symbol_file>:
	Remove.
fix PR symtab/15028

This fixes some derivation.exp regressions with "dwz -m".

The bug here is that the imported PU is given language_minimal.
However, it ought to be C++.

The "pretend language" machinery exists to solve this problem, but it
wasn't handled in process_psymtab_comp_unit.  So, this patch adds it
there.

Built and regtested, both normally and using "dwz -m", on x86-64
Fedora 18.

	PR symtab/15028:
	* dwarf2read.c (struct process_psymtab_comp_unit_data): New.
	(process_psymtab_comp_unit_reader): Use it.
	(process_psymtab_comp_unit): Update.  Add "pretend_language"
	argument.
	(dwarf2_build_psymtabs_hard): Update.
	(scan_partial_symbols): Pass CU's language to
