There might be cases where you describe an enum in isaspec and want it to use
for decoding but also for codegen with e.g. mako.
Lets have a look at the following exmaple:
<enum name="#cond">
<value val="0" display=""/> <!-- always: display nothing -->
<value val="1" display=".gt"/>
...
</enum>
In the decoding case we want that nothing gets displayed if #cond has the value of "0". For
codegen with mako this could result in the following C code:
enum PACKED cond {
COND_ = 0,
COND_GT = 1,
...
};
What you really want is this:
enum PACKED cond {
COND_ALWAYS = 0,
COND_GT = 1,
...
};
To make this possible introduce BitSetEnumValue class which represents
an isaspec xml enum. It holds the value, displayname and now a name.
With the __str__ method the old behaviour is still intact.

Allows every user of isaspec to add custom meta information
to any bitset. This can be quite handy if you want to know
how many sources your instruction have, if this instruction has
a dest or provide some names for sources that can be used
by some debug tools.
All you need is to sprinkle <meta> tags in the xml file and
provide custom attributes.
<meta has_dest="1" num_sources="3" .. />
With get_meta() method of any bitset you can get access to
the dict with all the attributes. get_meta() walks the whole
tree to collect all <meta> tags on the way to the root node.

If you have a repeating <display> substring you can replace this
substring with a template and reference the template name instead.
Saves from doing lot of copy&paste and makes general changes to the
substring much easier.

We'll implement layer ID reads in the frag shader with a varying read, but if
the VS doesn't write the varying we need to return 0 per the spec. Add a sysval
to detect that case so we can handle it at runtime without keys.

This is mostly a direct port of the GLSL IR code there are only
2 real functional changes.
1. The direct use of mesa symbol_table instead of glsl_symbol_table.
However since none of the extra functionality offered by
glsl_symbol_table was ever used here this can be seen as an
improvement.
2. Because interface blocks are lowered before this new nir linker
sees them we must explicitly skip them (they are validated
elsewhere) to avoid errors.

In the linear allocation only the parent (context) can be used
to allocate new children, so let's use an opaque type to identify
the linear context. This is similar to what's done in GC allocator.
Update the documentation and a couple of function names to
refer to linear context instead of linear parent.

That will make sure the include directories are passed on and also
make sure the generated headers are properly built before whoever code
depends on it. NIR dependency propagates that dependency too.
Since the right include directory is always propagated, we can remove
the extra "compiler/" prefix from the `#include`s in glsl_types.h.
Note: NIR has a special "header only" dependency, so include the
generated headers for compiler there too.
