glsl: Fix lack of i2u in lower_ubo_reference.

ir_binop_ubo_load takes unsigned integer operands.  However, the array
index used to compute these offsets may be a signed integer.  (For
example, see Piglit's spec/glsl-1.40/uniform_buffer/fs-bvec-array).

For some reason, we were missing an ir_binop_i2u cast, and ir_validator
was failing to catch that.

Without this change, ir_builder's type inference code broke for me when
writing a new optimization pass.

i965/fs: Skip emitting MACH/MOV for small integers.

The vector backend already implemented this optimization, but
surprisingly, we never bothered to implement it in the scalar backend.

In addition to saving two instructions, this eliminates a use of the

glsl: Make is_16bit_constant from i965 an ir_constant method.

The i965 MUL instruction doesn't natively support 32-bit by 32-bit
integer multiplication; additional instructions (MACH/MOV) are required.
However, we can avoid those if we know one of the operands can be
represented in 16 bits or less.  The vector backend's is_16bit_constant
static helper function checks for this.

We want to be able to use it in the scalar backend as well, which means
moving the function to a more generally-usable location.  Since it isn't
i965 specific, I decided to make it an ir_constant method, in case it
ends up being useful to other people as well.

automake: don't enable -Wl,--no-undefined on OpenBSD

OpenBSD does not have DT_NEEDED entries for libc by design,
over concerns how the symbols would be referenced after
changing the major version of the library.

So avoid -no-undefined checks on OpenBSD as they will fail.

v2: don't include the -no-undefined libtool option in the variable
    and change -Wl,--no-undefined references in Automake.inc as well.

glapi: Enable ES compatibility mode

Ages ago Chia-I added an ES compatibility flag to several of the various
generator scripts.  The intention was to bridge differences between ES
and desktop in Mesa builds without ES.  It doesn't appear that it has
ever been used.  Recent changes to static_dispatch status of several ES1
functions caused problems in desktop-only, non-shared-glapi builds.
Enabling the ES compatibility mode appears to fix these build problems.

This is kind of a duct tape solution to this problem.  As I mentioned in
the cover letter for the series that triggered the build problem, I
would like to make some major changes to the generator architecture and
the XML.  The whole point of the proposed architecture changes is to
better handle the differences between desktop GL and ES.  I think duct
tape is okay for now.

glapi: Remove support for "short string" mode

C89 has a fairly short minimum-maximum string length.  To support
compilers limited by the C89 limits, this script had a mode where it
would generate a character array instead of a giant string.  These were
functionally the same, but the code generated for the character array is
HUGE and difficult to read.

As far as I can tell, nothing in Mesa uses '-m short' any more.  The

stopped using '-m short' when we stopped tracking the generated files.
