Fix error in of_SUBI with wide results.
...
This patch fixes an error in the recent rework of of_SUBI.
It was doing a double bit inversion.

Better use of immediate operands.
...
Clarify that operands are typically 32bits, and have the code generator
make better use of this.
Also improve the %movi implementation to work well with marger vectors.
Add the %andi instruction to use immediate operands.

Optimize %div and %div/s
...
Use high radix long division to take advantage of the divide hardware
of the host computer. It looks brute force at first glance, but since
it is using the optimized arithmetic of the host processor, it is much
faster then implementing "fast" algorithms the hard way.

Optimize the %load/vp0 to use subarrays.
...
This instruction adds an integer value to the value being loaded. This
optimization uses subarrays instead of the += operator. This is faster
because the value is best loaded into the vector as a subarray anyhow.

Optimize/inline vvp_bit4_r AND, OR and vector set bit.
...
The AND and OR operators for vvp_bit4_t are slightly tweaked to be
lighter and inlinable.
The vvp_vector4_t::set_bit is optimized to do less silly mask fiddling.

Bring switch information out to the ivl_target API.

This involves defining the API for switches and cleaning up the
elaborated form to match the defined ivl_target API. Also add t-dll
code to support the ivl_switch_t functions, and add stub code that
checks the results.
