test: Fix build on MSVC
...
The MSVC compiler is very strict about variable declarations after
statements.
Move all the declarations of each block before any statement in the
same block to fix multiple instances of:
alpha-loop.c(XX) : error C2275: 'pixman_image_t' : illegal use of this
type as an expression

test: Switch to the new PRNG instead of old LCG
...
Wallclock time for running pixman "make check" (compile time not included):
----------------------------+----------------+-----------------------------+
| old PRNG (LCG) | new PRNG (Bob Jenkins) |
Processor type +----------------+------------+----------------+
| gcc 4.5 | gcc 4.5 | gcc 4.7 (simd) |
----------------------------+----------------+------------+----------------+
quad Intel Core i7 @2.8GHz | 0m49.494s | 0m43.722s | 0m37.560s |
dual ARM Cortex-A15 @1.7GHz | 5m8.465s | 4m37.375s | 3m45.819s |
IBM Cell PPU @3.2GHz | 23m0.821s | 20m38.316s | 16m37.513s |

But some tests got a particularly large boost. For example benchmarking and

Add alpha-loop test program
...
This tests what happens if you attempt to make an image with an alpha
map that has the image as its alpha map. This results in an infinite
loop in _pixman_image_validate(), so the test sets up a SIGALRM to
exit if it runs for more than five seconds.
