x11perf -all leads to Xorg crash on 8-STABLE

[Carlos A. M. dos Santos]

I just noticed that the CONFIGURE_ARGS in x11/pixman should disable
sse2 on AMD64, but this is not working:

> #0  0x000000080107c255 in pixman_blt_sse2 (src_bits=0x81344f000,
> dst_bits=0x804000000, src_stride=2400,
>    dst_stride=4096, src_bpp=32, dst_bpp=32, src_x=576, src_y=576,
> dst_x=3, dst_y=3, width=10, height=9)
>    at pixman-sse2.c:5330

I rebuilt and reinstalled the pixman with

# cd /usr/ports/x11/pixman
# make BATCH=yes CONFIGURE_ARGS='--disable-vmx --disable-arm-simd
--disable-mmx --disable-sse2' FORCE_PKG_REGISTER=yes install

This did not solve the problem, just gave me a different kind of crash:
