When targeting 32-bit Linux, we need to pass -msse2 to gcc to compile SSE2 intrinsics. However, -msse2 also gives gcc license to automatically generate SSE2 instructions wherever it pleases. This will crash our code on processors without SSE2 support. This change breaks the files with SSE2 intrinsics into separate targets, such that we can limit the scope of -msse2 to where it's needed. We no longer need to employ the WEBRTC_USE_SSE2 define; the build system decides when SSE2 is supported and compiles the appropriate files.
