* Combined llvm and llvm-lld: removed the separate llvm-lld package
and added llvm-lld as an optional add on to the llvm package (the
way several other llvm tools are maintained e.g. lldb)
* Added more lld hashes to llvm package
* The 'CppBackend' target doesn't exist for version 3.9.0 or later
so exclude it for later versions
* Was incorrectly specifying 'sparc' as a target for the 'sparc'
architecture - needed to specify 'Sparc'
* Fix issue #7248 building llvm: don't make the LLVMDemangle target
for llvm < 4.0.0
