With SSE2 version memcpy32, S32_Opaque_BlitRow32() in SkBlitRow_D32.cpp
has about 30% performance improvement. Here are the data on desktop
i7-3770.
before:
bitmap_scale_filter_90_90 8888: cmsecs = 2.01
bitmaprect_FF_filter_trans 8888: cmsecs = 3.61
bitmaprect_FF_nofilter_trans 8888: cmsecs = 3.57
bitmaprect_FF_filter_identity 8888: cmsecs = 3.53
bitmaprect_FF_nofilter_identity 8888: cmsecs = 3.53
bitmap_4444_update 8888: cmsecs = 4.84
bitmap_4444_update_volatile 8888: cmsecs = 4.81
bitmap_4444 8888: cmsecs = 4.81
after:
bitmap_scale_filter_90_90 8888: cmsecs = 1.83
bitmaprect_FF_filter_trans 8888: cmsecs = 2.36
bitmaprect_FF_nofilter_trans 8888: cmsecs = 2.36
bitmaprect_FF_filter_identity 8888: cmsecs = 2.60
bitmaprect_FF_nofilter_identity 8888: cmsecs = 2.63
bitmap_4444_update 8888: cmsecs = 3.30
bitmap_4444_update_volatile 8888: cmsecs = 3.30
bitmap_4444 8888: cmsecs = 3.29

General cleanup of optimization files for x86/SSEx.
Renamed the opts_check_SSE2.cpp file to _x86, since it's not specific
to SSE2. Commented out the ColorRect32 optimization, since it's
disabled anyway, to make it more visible.
Also fixed a lot of indentation, inclusion guards, spelling,
copyright headers, braces, whitespace, and sorting of includes.

Using explicitly indexed references allows some compilers to generate more efficient loops. For gcc 4.6.3:
613c18: 83 ea 10 sub $0x10,%edx
613c1b: 66 0f 7f 07 movdqa %xmm0,(%rdi)
613c1f: 66 0f 7f 47 10 movdqa %xmm0,0x10(%rdi)
613c24: 66 0f 7f 47 20 movdqa %xmm0,0x20(%rdi)
613c29: 66 0f 7f 47 30 movdqa %xmm0,0x30(%rdi)
613c2e: 48 83 c7 40 add $0x40,%rdi
613c32: 83 fa 0f cmp $0xf,%edx
613c35: 7f e1 jg 613c18 <_Z16sk_memset32_SSE2Pjji+0x38>
vs. previous:
613c18: 83 ea 10 sub $0x10,%edx
613c1b: 66 0f 7f 07 movdqa %xmm0,(%rdi)
613c1f: 66 0f 7f 47 10 movdqa %xmm0,0x10(%rdi)
613c24: 66 0f 7f 47 20 movdqa %xmm0,0x20(%rdi)
613c29: 48 83 c7 40 add $0x40,%rdi
613c2d: 83 fa 0f cmp $0xf,%edx
613c30: 66 0f 7f 47 f0 movdqa %xmm0,-0x10(%rdi)
613c35: 7f e1 jg 613c18 <_Z16sk_memset32_SSE2Pjji+0x38>
This yields a 0.2% - 1% improvement with the memset micro benchmarks, presumably due to avoiding a stall on the next store after the %rdi increment.

I have manually examined all of these diffs and restored a few files that
seem to require manual adjustment.
The following files still need to be modified manually, in a separate CL:
android_sample/SampleApp/AndroidManifest.xml
android_sample/SampleApp/res/layout/layout.xml
android_sample/SampleApp/res/menu/sample.xml
android_sample/SampleApp/res/values/strings.xml
android_sample/SampleApp/src/com/skia/sampleapp/SampleApp.java
android_sample/SampleApp/src/com/skia/sampleapp/SampleView.java
