[DWARF] Default lower bound should respect requested DWARF version. DWARF may define a default lower-bound for arrays in languages defined in a particular DWARF version. But the logic to suppress an unnecessary lower-bound attribute was looking at the hard-coded default DWARF version, not the version that had been requested. Also updated the list with all languages defined in DWARF v5. Differential Revision: http://reviews.llvm.org/D30484 llvm-svn: 296652

; DW_LANG_C_plus_plus_11 is new in DWARF v5, so if we use that with
; DWARF v4, we should get the DW_AT_lower_bound attribute.

Re-land "[llvm-dwarfdump] Print type names in DW_AT_type DIEs" This patch adds printing for DW_AT_type DIEs like it is already the case for DW_AT_specification DIEs. This is a rather naive approach and only a start. We should have pretty printers for different languages. Recommit after being reverted in r315299.

Canonicalize the representation of empty an expression in DIGlobalVariableExpression This change simplifies code that has to deal with DIGlobalVariableExpression and mirrors how we treat DIExpressions in debug info intrinsics. Before this change there were two ways of representing empty expressions on globals, a nullptr and an empty !DIExpression(). If someone needs to upgrade out-of-tree testcases: perl -pi -e 's/(!DIGlobalVariableExpression\(var: ![0-9]*)\)/\1, expr: !DIExpression())/g' <MYTEST.ll> will catch 95%. llvm-svn: 312144
