cp-demangle.c (d_encoding): When DMGL_PARAMS is not set...

Browse Source 
* cp-demangle.c (d_encoding): When DMGL_PARAMS is not set, strip
	CV-qualifiers from D_COMP_LOCAL_NAME right subtree.
	* cplus-dem.c (demangle_arm_hp_template): Set DMGL_PARAMS when
	demangling template parameters.
	* testsuite/test-demangle.c (fail): New static function.
	(main): Support new options in input file: --no-params,
	--is-v3-ctor, and --is-v3-dtor.
	* testsuite/demangle-expected: Add --no-params to most tests, and
	add the correct result when parameters are not demangled.  Add
	some simple tests for V3 constructor/destructor recognition.

Supported options:
--format=<name> Sets the demangling style.
--no-params There are two lines of expected output; the first
is with DMGL_PARAMS, the second is without it.
--is-v3-ctor Calls is_gnu_v3_mangled_ctor on input; expected
output is an integer representing ctor_kind.
--is-v3-dtor Likewise, but for dtors.
#define FORMATS "--format="
#define FORMATL (sizeof FORMATS - 1)
For compatibility, just in case it matters, the options line may be
empty, to mean --format=auto. If it doesn't start with --, then it
may contain only a format name.
