8346c59e6a Producing a DW_FORM_addr for DW_AT_stmt_list is probably correct, but 
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.

3506ad5c7f 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.

2d8861a690 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.

7d7ac5512a Emit debug info for global variables first. 
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

f288e23b3f This mechanical patch moves type handling into CompileUnit from DwarfDebug. In case of multiple compile unit in one object file, each compile unit is responsible for its own set of type entries anyway. This refactoring makes this obvious.

39ac307002 Do not emit DW_AT_upper_bound and DW_AT_lower_bound for unbouded array. 
If lower bound is more then upper bound then consider it is an unbounded array.
An array is unbounded if non-zero lower bound is same as upper bound.
If lower bound and upper bound are zero than array has one element.
