bitvec: Force inlining of bitvec_set_bit_pos/bitvec_set_bit

The PCU is using bitvec_write_field a lot but on the
arm-poky-linux-gnueabi-gcc v4.8.1 the calls to set_bit and
set_bit_pos are not inlined. The inlined variant has been
a more quick for the PCU compressed bitmap decompression
testcase.

Used objdump -d to look at the bitvec_write_field before and
after the change. The branch to bitvec_set_bit is gone and a
inlined version has been used.
