Remove _mesa_is_type_integer and _mesa_is_enum_format_or_type_integer

The comment for _mesa_is_type_integer is confusing because it says that it
returns whether the type is an “integer (non-normalized)” format. I don't
think it makes sense to say whether a type is normalized or not because it
depends on what format it is used with. For example, GL_RGBA+GL_UNSIGNED_BYTE
is normalized but GL_RGBA_INTEGER+GL_UNSIGNED_BYTE isn't. If the normalized
comment is just a mistake then it still doesn't make much sense because it is
missing the packed-pixel types such as GL_UNSIGNED_INT_5_6_5. If those were
added then it effectively just returns type != GL_FLOAT.

That function was only used in _mesa_is_enum_format_or_type_integer. This
function effectively checks whether the format is non-normalized or the type
is an integer. I can't think of any situation where that check would make
sense.

As far as I can tell neither of these functions have ever been used anywhere
so we should just remove them to avoid confusion.

These functions were added in 9ad8f431b2a47060bf05517246ab0fa8d249c800.

llvmpipe: increase number of queries which can be binned simultaneously to 64

Gallium (but not OpenGL) does allow nesting of queries, but there's no
limit specified (d3d10 has no limit neither). Nevertheless, for practical
purposes we need some limit in llvmpipe, otherwise we'd need more complex
handling of queries as we need to keep track of all binned queries (this
only affects queries which gather data past setup). A limit of 16 is too
small though, while 64 would suffice.

freedreno: fix for null textures

Some apps seem to give us a null sampler/view for texture slots which
come before the last used texture slot.  In particular 0ad triggers
this.
