[CMake] Put libcxx-specific module directories to the front of CMAKE_MODULE_PATH.

Alexey Samsonov · Alexey Samsonov · commit 18595440712c · 2013-09-30T09:10:01.000Z
Otherwise if libcxx is built as an LLVM external project (after r191624),
"include(config-ix)" will include config-ix.cmake from LLVM, not from libcxx,
which will result in misconfigured build tree.
