Orlando Cazalet-Hyams ed67bf8d2f Resubmit "[DebugInfo] Update loop metadata for inlined loops"
This reverts commit 95805bc425.
I've squashed the test fix into this commit.

[DebugInfo] Update loop metadata for inlined loops

Currently, when a loop is cloned while inlining function (A) into function (B)
the loop metadata is copied and then not modified at all. The loop metadata can
encode the loop's start and end DILocations. Therefore, the new inlined loop in
function (B) may have loop metadata which shows start and end locations residing
in function (A).

This patch ensures loop metadata is updated while inlining so that the start and
end DILocations are given the "inlinedAt" operand. I've also added a regression
test for this.

This fix is required for D60831 because that patch uses loop metadata to
determine the DILocation for the branches of new loop preheaders.
