tcg: Fix compiler error (comparison of unsigned expression)
When qemu is configured with --enable-debug-tcg, gcc throws this warning (or error with -Werror): tcg/tcg.c:1030: error: comparison of unsigned expression >= 0 is always true Fix it by removing the >= 0 part. The type cast to 'unsigned' catches negative values of op (which should never happen). This is a modification of Hollis Blanchard's patch.
