We prefix names with an underscore to make them "safe" C identifiers
when necessary. For example, a value of "32x32" would become "_32x32".
However, when specifying something like
<field ... prefix="BLOCK_SIZE">
<value name="32x32" value="0"/>
</field>
we already have a prefix that makes the field name safe. We'd rather
generate a name with a single underscore, i.e.
#define BLOCK_SIZE_32x32 0
rather than
#define BLOCK_SIZE__32x32 0
This also fixes up affected defines in crocus.

When a <field> tag has multiple <value> children, listing symbolic names
for possible field values, we generate #defines for each value, with an
optional prefix. I don't know why, but this code was checking whether
self.default is None. We want to generate the same list of #defines,
with a prefix, regardless of whether the field has a default value
specified or not.

This asserts that the value supplied is non-zero. Useful for things
like MOCS fields on modern platforms where we really want to avoid
setting it to 0 (uncached).
mbz types cannot be flagged as nonzero.

There are some fields which Must Be Zero, and we don't want to allow
setting them from the template struct, but we do want them in the XML
to allow them to be decoded properly, and for documentation purposes.
This adds a new "mbz" type, much like "mbo", except it doesn't set
anything in the struct. We also update the decoder to handle it.

Python's assert can take both a condition and a string, which will cause
it to print the string if the assertion trips. (You can't use parens as
that creates a tuple.) Doing "condition and string" works in C, but
doesn't have the desired effect in Python.

Some instructions contain fields that are either an address or a value
of some type based on the content of other fields, such as clear color
values vs address. That works fine if these fields are in the less
significant dword, the lower 32 bits of the address, because they get
OR'ed with the address. But if they are in the higher 32 bits, they get
discarded.
On Gen10 we have fields that share space with the higher 16 bits of the
address too. This commit makes sure those fields don't get discarded.
