Add some casts in tgt-vhdl to remove warnings.
...
The Cygwin compiler is a bit picky. This patch adds some casts
to remove compilation warnings. In the past I have had warnings
off because of problems with the STL, but we may as well get
rid of the warnings we can. It also does not recognize that an
assert(0) or assert(false) ends a routine so it complains about
no return at end of function or variables not being defined.

Move VHDL global state management to a single file
...
The new state.cc/hh file now manages all the global
state that we maintain while generating VHDL. This
should make the code a bit tidier.

Tidy up reduction functions in support.cc
...
This removes some unnecessary code duplication as the functions
only differ (or need to differ) in two places.

Support conversion of (un)signed to std_logic

Take the least-significant bit. This fixes a couple of broken
test cases.

Always user Ternary_* support functions for ternary assignments
...
Previously the code generator expanded ternary assignments to
and `if' statement. This patch replaces that with a single assignment
and a call to a Ternary_* support function. This will make it
much easier to support multiple lvals later.
