Quick compiler: Fix MIPS build

b/16484538

In debug builds, the Quick compiler frequently runs a sanity checker
over the register pool.  Among other things, it attempts to verify
consistent representation of register pairs.  However, a register's
"wide" flag is meaningful only when the register pair is associated
with a Dalvik wide value (sreg != INVALID_SREG) rather than a temp
wide value.

The MIPS build was tripping over this bad assertion.  Fixed here.

Always setup the native bridge library

... even if the string is empty. This will initialize the native bridge
library but mark it as unavailable.

- also, rename native_bridge_library_path to
native_bridge_library_filename to be closer to the actual meaning (it's
just the filename without any path).
