Pavel Labath e992eb498a Recommit "[DWARF] Add an api to get "interpreted" location lists" ... This recommits 089c0f581492cd6e2a3d2927be3fbf60ea2d7e62, which was reverted due to failing tests on big endian machines. It includes a fix which I believe (I don't have BE machine) should fix this issue. The fix consists of correcting the invocation DWARFYAML::EmitDebugSections, which was missing one (default) function arguments, and so didn't actually force the little-endian mode. The original commit message follows. Summary: This patch adds DWARFDie::getLocations, which returns the location expressions for a given attribute (typically DW_AT_location). It handles both "inline" locations and references to the external location list sections (currently only of the DW_FORM_sec_offset type). It is implemented on top of DWARFUnit::findLoclistFromOffset, which is also added in this patch. I tried to make their signatures similar to the equivalent range list functionality. The actual location list interpretation logic is in DWARFLocationTable::visitAbsoluteLocationList. This part is not equivalent to the range list code, but this deviation is motivated by a desire to reuse the same location list parsing code within lldb. The functionality is tested via a c++ unit test of the DWARFDie API.
