llc/test: Explicitly enable extended initialiser lists

To support extended initialiser lists some platforms (at least debian
squeeze) require to add -std=c++0x or -std=gnu++0x to CXXFLAGS. While
that option is deprecated on newer platforms (at least gcc 4.8) this
options is still supported on every platform currently in use.

This commit adds -std=gnu++0x to the CXXFLAGS used to compile
LlcTest.cpp.
