Avoid vector element insert type mismatch. Subzero silently allows inserting a 32-bit integer into a vector with 16-bit elements. This generates a pinsrd instruction, which requires SSE4.1, even when specifying to only support SSE2. This change emits a pinsrw instruction instead, which is SSE2.

SwiftShader is a high-performance CPU-based implementation of the OpenGL ES and Direct3D 9 graphics APIs12. Its goal is to provide hardware independence for advanced 3D graphics.
The SwiftShader libraries act as drop-in replacements for graphics drivers.
On Windows, most applications can be made to use SwiftShader's DLLs by placing them in the same folder as the executable. On Linux, the LD_LIBRARY_PATH environment variable or -rpath linker option can be used to direct applications to search for shared libraries in the indicated directory first.
