[Debuginfo][NFC] Avoid double calling of DWARFDie::find(DW_AT_name).
Summary:
Current implementation of DWARFDie::getName(DINameKind Kind) could
lead to double call to DWARFDie::find(DW_AT_name) in following
scenario:
getName(LinkageName);
getName(ShortName);
getName(LinkageName) calls find(DW_AT_name) if linkage name is not
found. Then, it is called again in getName(ShortName). This patch
alows to request LinkageName and ShortName separately
to avoid extra call to find(DW_AT_name).
It helps D74169 to parse clang debuginfo faster(~1%).
