Move global FlagSfi variables to common module
When built as nexe, llc is configured and built for one arch only.
Variables FlagSfiData, FlagSfiLoad, FlagSfiStore, FlagSfiStack, and
FlagSfiBranch have to availabe for MIPS as well, so this change moves
them from ARM-only code to common code.
BUG= building pnacl-llc.nexe for MIPS fails
TEST= build sandboxed tools for MIPS
