Fix a bug that prevents global variables from having a DW_OP_deref.
For local variables the first DW_OP_deref is consumed by turning the
location kind into a memeory location, but that only makes sense for
values that are in a register to begin with, which cannot happen for
global variables that are attached to a symbol.
rdar://problem/39741860
This reapplies r330970 after fixing an uncovered bug in r331086 and
working around the situation caused by it.
