[DWARF] Emit DW_AT_call_return_pc as an address
This reverts D53469, which changed llvm's DWARF emission to emit
DW_AT_call_return_pc as a function-local offset. Such an encoding is not
compatible with post-link block re-ordering tools and isn't standards-
compliant.
In addition to reverting back to the original DW_AT_call_return_pc
encoding, teach lldb how to fix up DW_AT_call_return_pc when the address
comes from an object file pointed-to by a debug map. While doing this I
noticed that lldb's support for tail calls that cross a DSO/object file
boundary wasn't covered, so I added tests for that. This latter case
exercises the newly added return PC fixup.
The dsymutil changes in this patch were originally included in D49887:
the associated test should be sufficient to test DW_AT_call_return_pc
encoding purely on the llvm side.

Commit a2cc80bc95703b99afefddb1d9d545c639ac4ff5 by Vedant Kumar
DebugInfo: Factor out logic to update locations in MD_loop metadata, NFC
Factor out the logic needed to update debug locations contained within
MD_loop metadata.
This refactor is preparation for a future change that also needs to
rewrite MD_loop metadata.

Commit 34ba96a3d49e14abb2a36114a4ed6f97e1b9a9ee by danilo.carvalho.grael
[NFC][IndVarSimplify] remove duplicate code in
widenWithVariantLoadUseCodegen.
Summary: Duplicate code in widenWithVariantLoadUseCodegen is removed and
also use assert to check unknown extension type as it should be filtered
out by the pre condition check before calling this function.
