Generate synthesisable code for sequential processes
...
Whilst adding `wait until ...' at the end of every
process is a valid translation of the input, it is not
actually synthesisable in at least one commercial
synthesiser (XST). According to the XST manual the
correct template is to use `wait until ...' at the
start of sequential processes and `wait on ...'
(equivalent to `wait until ...' with 'Event on all
the signals) at the end of combinatorial processes.
This patch implements that.

Fix initialisation order
...
Initial processes set a magic flag in the code generator
which allows it to push constant assignments into the
VHDL signal initialisation and omit the assignment.
However, it should only do this if the signal has not
already been read (otherwise the previous read would
not get the undefined value as expected)
