it is both inefficient and unexpected by dwarfdump. Change to
a DW_FORM_data4.

While in here, change the predicate name to reflect that the position
is not really absolute (it is an offset), just that the linker needs a
relocation.

Tighten up check for empty (i.e. no meaningful debug info) module. This fixes dwarf-die2.c test case from gcc test suite.

Even if the subprogram is going to use AT_specification, emit DW_AT_MIPS_linkage_name. This helps gdb and fixes var-path-expr.exp regression reported by gdb testsuite.

If the front end has emitted llvm.dbg.cu and other debug info anchors (clang does it now) then use them directly. This saves one scan of entire module, to collect debug info, which in turns saves few machine cycles at compile time.

This works around a limitation in gdb which is reported by following inherit.exp test failures from gdb testsuite.

gdb.cp/inherit.exp: print g_vB.vB::vb
gdb.cp/inherit.exp: print g_vB.vB::vx
gdb.cp/inherit.exp: print g_vC.vC::vc
gdb.cp/inherit.exp: print g_vC.vC::vx
gdb.cp/inherit.exp: print g_vD.vB::vb
