Richard Henderson 886902ece7 target/arm: Use uint32_t instead of bitmap for sve vq's 
The bitmap need only hold 15 bits; bitmap is over-complicated.
We can simplify operations quite a bit with plain logical ops.

The introduction of SVE_VQ_POW2_MAP eliminates the need for
looping in order to search for powers of two.  Simply perform
the logical ops and use count leading or trailing zeros as
required to find the result.
