ir_to_mesa: Emit warnings instead of errors for IR that can't be lowered
Rely on the driver to do the right thing. This probably means falling
back to software. Page 88 of the OpenGL 2.1 spec specifically says:
"A shader should not fail to compile, and a program object should
not fail to link due to lack of instruction space or lack of
temporary variables. Implementations should ensure that all valid
shaders and program objects may be successfully compiled, linked
and executed."
There is no provision for saying "No" to a valid shader that is
difficult for the hardware to handle, so stop doing that.
On i915 this causes a large number of piglit tests to change from FAIL
to WARN. The warning is because the driver still emits messages to
stderr like "i915_program_error: Unsupported opcode: BGNLOOP".
It also fixes ES2 conformance CorrectFull_frag and CorrectParse1_frag
on i915 (and probably other hardware that can't handle loops).

glsl_to_tgsi: stop generating Mesa IR
Before, it was still generating unused Mesa IR as a remnant of ir_to_mesa, and
depended on some of the information from it.

mesa: fix segfault when no Mesa IR is generated

st/mesa: Add a GLSL IR to TGSI translator.
It is still a work in progress at this point, but it produces working and
reasonably well-optimized code.
Originally based on ir_to_mesa and st_mesa_to_tgsi, but does not directly use
Mesa IR instructions in TGSI generation, instead generating TGSI from the
intermediate class glsl_to_tgsi_instruction. It also has new optimization
passes to replace _mesa_optimize_program.

glsl: improve the accuracy of the atan(x,y) builtin function.
The previous formula for atan(x,y) returned a value of +/- pi whenever
|x|<0.0001, and used a formula based on atan(y/x) otherwise. This
broke in cases where both x and y were small (e.g. atan(1e-5, 1e-5)).
This patch modifies the formula so that it returns a value of +/- pi
whenever |x|<1e-8*|y|, and uses the formula based on atan(y/x)
otherwise.

glsl: improve the accuracy of the asin() builtin function.
The previous formula for asin(x) was algebraically equivalent to:
sign(x)*(pi/2 - sqrt(1-|x|)*(A + B|x| + C|x|^2))
where A, B, and C were arbitrary constants determined by a curve fit.
This formula had a worst case absolute error of 0.00448, an unbounded
worst case relative error, and a discontinuity near x=0.
Changed the formula to:
sign(x)*(pi/2 - sqrt(1-|x|)*(pi/2 + (pi/4-1)|x| + A|x|^2 + B|x|^3))
where A and B are arbitrary constants determined by a curve fit. This
has a worst case absolute error of 0.00039, a worst case relative
error of 0.000405, and no discontinuities.
I don't expect a significant performance degradation, since the extra
multiply-accumulate should be fast compared to the sqrt() computation.
