Currently uint64_t_to_bitmask(..) is used in combination with
the pattern 'match'. This only works for values smaller then
64 bit. Add support for bigger isa sizes.

This is necessary for some ops which have slightly different encoding on
a4xx/a5xx, but are otherwise identical. This helps keeping the compiler
from having to worry about these details and creating separate ops.

Add function prototypes for generated expr evaluators, to avoid a use-
before-declaration issue if an expression references a derived field.

If an <override> overrides the definition of a field, don't emit
encoding for both the override's definition and the fallback. (See
"SAMP" in #cat5-src3). It is harmless currently, because (in this
case) it will just re-encode the low bits of "SAMP". But when we
start asserting on that the field being encoded fits in the allowed
number of bits, the re-encoding of the fallback field definition
will start triggering asserts.

bitset encoding tends to have a lot of duplication, for ex. many
instructions with the same encoding modulo the fixed pattern. Now that
encode_bitset is split out into it's own template, so that we can
capture the result, use a hash table to de-duplicate the bitset encoding
into "snippet" functions so that bitset cases with identical encoding
can re-use the same generated code.

In the next patch, we are going to want to be able to capture the result
of rendering the template as a py variable, which I don't think you can
do otherwise with a <%def>.
