[dwarfdump] Pretty print location expressions and location lists Summary: Based on Fred's patch here: https://reviews.llvm.org/D6771 I can't seem to commandeer the old review, so I'm creating a new one. With that change the locations exrpessions are pretty printed inline in the DIE tree. The output looks like this for debug_loc entries: DW_AT_location [DW_FORM_data4] (0x00000000 0x0000000000000001 - 0x000000000000000b: DW_OP_consts +3 0x000000000000000b - 0x0000000000000012: DW_OP_consts +7 0x0000000000000012 - 0x000000000000001b: DW_OP_reg0 RAX, DW_OP_piece 0x4 0x000000000000001b - 0x0000000000000024: DW_OP_breg5 RDI+0) And like this for debug_loc.dwo entries: DW_AT_location [DW_FORM_sec_offset] (0x00000000 Addr idx 2 (w/ length 190): DW_OP_consts +0, DW_OP_stack_value Addr idx 3 (w/ length 23): DW_OP_reg0 RAX, DW_OP_piece 0x4) Simple locations without ranges are printed inline: DW_AT_location [DW_FORM_block1] (DW_OP_reg4 RSI, DW_OP_piece 0x4, DW_OP_bit_piece 0x20 0x0) The debug_loc(.dwo) dumping in changed accordingly to factor the code.

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.
