[PATCH] D37932: [DebugInfo] Move the "indirect" bit to the location interval map

[Reid Kleckner via Phabricator via llvm-commits]

rnk created this revision.
Herald added a subscriber: hiraditya.

A single UserValue, which approximates a user variable, may have many
DBG_VALUE instructions that disagree about whether the variable is in
memory or in a virtual register. This will become much more common once
we have llvm.dbg.addr.

Before this change, we would get two UserValues: one for direct and one
for indirect DBG_VALUE instructions describing the same variable.  Now
we get one.

FIXME: Needs tests, don't submit yet
