[cairo] Patches for speeding up _cairo_fixed_from_double

Attached are patches resulting from the discussion here:
http://lists.freedesktop.org/archives/cairo/2006-October/008285.html
First one defines an autoconf macro AX_C_FLOAT_WORDS_BIGENDIAN that
uses a similar technique as AC_C_BIGENDIAN to avoid having to actually
run code to determine the endianness (thanks again to Owen for the
tip).
Then there's the new _cairo_fixed_from_double that uses
FLOAT_WORDS_BIGENDIAN to pull off the magic number trick in a portable
manner.
Finally, I put together a new performance test to show off the new
speedup. This was necessary as no current tests really exercise the
API calls where conversion takes place. I don't really recommend that
this make it into the main performance suite, as it's pretty specific
to this particular case, but I'm including it here for posterity.
Both the autoconf macro and _cairo_fixed_from_double code are perhaps
overly documented, but they both use pretty unusual techniques, so I
figured they could use the extra attention.
Speedup (detailed diffs attached):
On my Pentium M (1.8GHz) I saw 2.5-3x speeup on my new
pattern_create_radial test. Several of the text_* tests saw a 1.2-1.4x
speedup.
On the same box, I changed over to use software floating point (long
story, hollar if you want details) and also saw a ~3x speedup on the
pattern_create_radial test (the actual magnitudes were quite
different, of course). Again, moderate speedups with the text tests,
but here we see a 1.5x speedup on the tessellate tests (still using
the old tessellator, though). Although the exact amount of speedup
seen on the Nokia 770 will likely be different, I think it will be in
the same ballpark. Anyone with one willing to test?
On a side note, I tried inlining the function to see what would
happen, and I got a 471x slowdown. Pretty bizarre; I'll have to look
into that later.

Subject: [PATCH] Add autoconf macro AX_C_FLOAT_WORDS_BIGENDIAN
The symbol that this macro defines (FLOAT_WORDS_BIGENDIAN) can be used
to make double arithmetic tricks portable.

+/* This is the "magic number" approach to converting a double into fixed
+ * point as described here:
+ *
+ * http://www.stereopsis.com/sree/fpu2006.html (an overview)
+ * http://www.d6.com/users/checker/pdfs/gdmfp.pdf (in detail)
+ *
+ * The basic idea is to add a large enough number to the double that the
+ * literal floating point is moved up to the extent that it forces the
+ * double's value to be shifted down to the bottom of the mantissa (to make
+ * room for the large number being added in). Since the mantissa is, at a
+ * given moment in time, a fixed point integer itself, one can convert a
+ * float to various fixed point representations by moving around the point
+ * of a floating point number through arithmetic operations. This behavior
+ * is reliable on most modern platforms as it is mandated by the IEEE-754
+ * standard for floating point arithmetic.
+ *
+ * For our purposes, a "magic number" must be carefully selected that is
+ * both large enough to produce the desired point-shifting effect, and also
+ * has no lower bits in its representation that would interfere with our
+ * value at the bottom of the mantissa. The magic number is calculated as
+ * follows:
+ *
+ * (2 ^ (MANTISSA_SIZE - FRACTIONAL_SIZE)) * 1.5
+ *
+ * where in our case:
+ * - MANTISSA_SIZE for 64-bit doubles is 52
+ * - FRACTIONAL_SIZE for 16.16 fixed point is 16
+ *
+ * Although this approach provides a very large speedup of this function
+ * on a wide-array of systems, it does come with two caveats:
+ *
+ * 1) It uses banker's rounding as opposed to arithmetic rounding.
+ * 2) It doesn't function properly if the FPU is in single-precision
+ * mode.

Subject: [PATCH] Add new perf test "pattern_create_radial"
This test is really just for hammering the double to fixed-point conversion
(in _cairo_fixed_from_double) that happens as doubles from API calls gets
translated into internal cairo fixed-point numbers.
Because it's not generally useful, I don't recommend that it become part of
the main cairo performance test. But hey, it might come in handy for someone
else.
