I did test this locally before sending it out, and the -resource-dir arg passed to cc1 is relative with this patch:

  $ bin/clang-cl -no-canonical-prefixes -c test.cc -###

driver.cpp handles this directly here http://llvm-cs.pcc.me.uk/tools/clang/tools/driver/driver.cpp#54 and here http://llvm-cs.pcc.me.uk/tools/clang/tools/driver/driver.cpp#390 -- what's the problem with the InitLLVM call you point at?
