Seems in case of 32-bit library, usage of msse2 makes
some stack corruption or incorrect instructions.
Usage with mstackrealign fixes that case.
v2: Fixed meson.
v3: Definition of c_sse2_args moved on the top (L.Landwerlin).
Added mstackrealign for Android's mks where msee4.1 is used.
v4: Added for Vulkan also.

Fixes: 6b05c080f202 (i965: Compile with -msse3)
Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=107779
