Specify that the operation only applies to the x component, not
per-component as previously specified. This is unnecessary for GL and
creates additional complications for images which need to support these
operations as well.

This patch adds support for a set of double opcodes
to TGSI. It is an update of work done originally
by Michal Krol on the gallium-double-opcodes branch.
The opcodes have a hint where they came from in the
header file.
v2: add unsigned/int <-> double
v2.1: update docs.
v3: add DRSQ (Glenn), fix review comments (Glenn).
v4: drop DDIV
v4.1: cleanups, fix some docs bugs, (Ilia)
rework store_dest and fetch_source fns. (Ilia)
4.2: fixup float comparisons (Ilia)
This is based on code by Michael Krol <michal@vmware.com>
Roland and Glenn also reviewed earlier versions.

since the address reg holds integer values, ARL/ARR do an implicit float-to-int
conversion, so clarify that. Thus it is also incorrect to say that FLR really
does the same as ARL.

Plus a new PIPE_CAP_VERTEXID_NOBASE query. The idea is that drivers not
supporting vertex ids with base vertex offset applied (so, only support
d3d10-style vertex ids) will get such a d3d10-style vertex id instead -
with the caveat they'll also need to handle the basevertex system value
too (this follows what core mesa already does).
Additionally, this is also useful for other state trackers (for instance
llvmpipe / draw right now implement the d3d10 behavior on purpose, but
with different semantics it can just do both).
Doesn't do anything yet.
And fix up the docs wrt similar values.
v2: incorporate feedback from Brian and others, better names, better docs.

The previous language was a bit misleading, since it sounded like
w was interpolated then the reciprocal calculated which isn't what
should be happening.

FWIW, the html that Sphinx 1.1.3 generates for the math expressions

Add documentation for TEX2/TXL2/TXB2 tgsi opcodes. Also, the texture opcode
documentation wasn't very accurate so fix this up a bit.
