Remove test sglib-listinsertsort1.

The two tests sglib-listinsertsort and sglib-listinsertsort1 were
basically identical.  By the time macro expansion had occurred the
only difference would depend on whether the compiler chose to inline a
function or not, not sufficiently different to justify being a
separate test.

Merge these two tests into one, I've taken the code from
sglib-listinsertsort1, but renamed it to sglib-listinsertsort.

ChangeLog:

	* configure.ac: Remove sglib-listinsertsort1.
	* configure: Regenerate.
	* src/sglib-listinsertsort/Makefile.am: Remove general automake
	HOWTO comment.
	* src/sglib-listinsertsort/Makefile.in: Regenerate.
	* src/sglib-listinsertsort/listinsertsort.c: Copied from old
	listinsertsort1.
	* src/sglib-listinsertsort/sglib.h (SGLIB_LIST_LEN): Remove
	declaraion of _ce_.
	* src/sglib-listinsertsort1/Makefile.am: Removed.
	* src/sglib-listinsertsort1/Makefile.in: Removed.
	* src/sglib-listinsertsort1/listinsertsort1.c: Removed.
	* src/sglib-listinsertsort1/sglib.h: Removed.
Remove all the gdb-* tests.

These tests, taken from the gdb testsuite are not representetive of
any real work load, they are artificial tests designed to exercise
features of the debugger.

Tests removed gdb-advance, gdb-all-types, gdb-anon, gdb-arrayidx,
gdb-async, gdb-auxv, gdb-bitfields, gdb-constvars, gdb-store.
