glsl: Don't lose precision qualifiers when encountering "centroid".
Mesa fails to retain the precision qualifier when parsing:
#version 300 es
centroid in mediump vec2 v;
Consider how the parser's type_qualifier production is applied.
First, the precision_qualifier rule creates a new ast_type_qualifier:
<precision: mediump>
Then the storage_qualifier rule creates a second one:
<flags: in>
and calls merge_qualifier() to fold in any previous qualifications,
returning:
<flags: in, precision: mediump>
Finally, the auxiliary_storage_qualifier creates one for "centroid":
<flags: centroid>
it then does $$ = $1 and $$.flags |= $2.flags, resulting in:
<flags: centroid, in>
Since precision isn't stored in the flags bitfield, it is lost. We need
to instead call merge_qualifier to combine all the fields.
