a98c0e91c7 dwarf2out.c: Pass one cv_quals argument instead of two for const and volatile. 
modified_type_die and add_type_attribute take two separate arguments
for whether the type should be const and/or volatile. To help add
more type modifiers pass the requested modifiers as one cv_quals argument
to these functions. And introduce helper function decl_quals to extract
additional cv_quals from declaration trees.

DWARFv3 added restrict_type [PR debug/59051] and DWARFv5 has proposals
for atomic_type and aligned_type. Which will be easier to implement based
on this change.

a6dad7b658 Add guality [p]type test. 
Add a new type:var variant to the guality.exp testsuite to check that
gdb gets the correct type for a variable or function. To use it in a
guality test add something like:

/* { dg-final { gdb-test 50 "type:main" "int (int, char **)" } } */

Which will put a breakpoint at line 50 and check that the type of "main"
equals "int (int, char **)" according to gdb. The test harness will make
sure to squash all extra whitespace/newlines that gdb might use to make
comparisons of large structs easy.

gcc/testsuite/ChangeLog

	* lib/gcc-gdb-test.exp (gdb-test): Handle type:var for gdb ptype
	matching. Catch '<unknown type in ' to recognize older gdb versions.
