Subject: [PATCH] fix a llvm compilation error due to header file reshuffle
MIME-Version: 1.0
Content-Type: text/plain; charset=utf8
Content-Transfer-Encoding: 8bit

llvm upstream https://reviews.llvm.org/D119723 removed
header file llvm/DebugInfo/DWARF/DWARFCompileUnit.h from
llvm/DebugInfo/DWARF/DWARFContext.h and this
caused bcc compilation failure:

  ...
  .../src/cc/bcc_debug.cc: In member function ‘void ebpf::SourceDebugger::dump()’:
  .../src/cc/bcc_debug.cc:186:69: error: no matching function for call to
   ‘llvm::DWARFContext::getLineTableForUnit(llvm::DWARFCompileUnit*&)’
     const DWARFLineTable *LineTable = DwarfCtx->getLineTableForUnit(CU);
                                                                     ^
  In file included from /home/yhs/work/bcc/src/cc/bcc_debug.cc:22:
  ...

Similar to fix in https://reviews.llvm.org/D119723, let us explicitly
add llvm/DebugInfo/DWARF/DWARFCompileUnit.h in the .cc file.
