Eric Christopher bb69a27dbc Use DW_FORM_flag_present to save space in debug information if we're 
not in darwin gdb compat mode.

Fixes rdar://10975088

Eric Christopher acb7115bde Remove the DW_AT_MIPS_linkage name attribute when we don't need it 
output (we're emitting a specification already and the information
isn't changing) and we're not in old gdb compat mode.

Saves 1% on the debug information for a build of llvm.

Eric Christopher b1b9451337 Temporarily revert c23b933d5f8be9b51a1d22e717c0311f65f87dcd. It's causing 
failures in the debug testsuite and possibly PR13486.

Eric Christopher 86ca9f9e11 Add a DW_AT_high_pc for CUs that are a single address range. Update 
all tests accordingly.

Fixes PR13351.

Eric Christopher 7734ca2891 For types with a parent of the compile unit make sure and emit 
the DECL information.

Eric Christopher 7dd54fb695 Revert the removal of DW_AT_MIPS_linkage_name when we aren't putting 
out the DW_AT_name. Older gdbs unfortunately still use it to
disambiguate member functions in templated classes (gdb.cp/templates.exp).

Eric Christopher 5cd2a9d98e Only add DW_AT_prototyped if we're working with a C-like language. 
Worth another 45k (1%) off of a large C++ testcase.

Eric Christopher 8575790912 There's no need for a DW_AT_byte_size on a pointer type. 
Part of rdar://10493979 where it reduces by about .5% (10k)

Rafael Espindola e7cc8bff82 The dwarf standard says that the only differences between a out-of-line 
instance and a concrete inlined instance are the use of DW_TAG_subprogram
instead of DW_TAG_inlined_subroutine and the who owns the tree.

We were also omitting DW_AT_inline from the abstract roots. To fix this,
make sure we mark abstract instance roots with DW_AT_inline even when
we have only out-of-line instances referring to them with DW_AT_abstract_origin.

FileCheck is not a very good tool for tests like this, maybe we should add
a -verify mode to llvm-dwarfdump.
