r300/compiler: Move declaration before code.
Fixes these GCC warning on linux-x86 build. radeon_optimize.c: In function ‘constant_folding’: radeon_optimize.c:419: warning: ISO C90 forbids mixed declarations and code radeon_optimize.c:425: warning: ISO C90 forbids mixed declarations and code radeon_optimize.c:432: warning: ISO C90 forbids mixed declarations and code
