no-sse2.patch: remove -ffloat-store, fix DirectConvolver FTBFS

* Remove the -ffloat-store workaround: The media player issue that
  caused problems with x87 floating point (and ultimately made upstream
  require SSE2) should already be fixed / worked around by:
  https://crrev.com/d2c745b13c93ecff5108bed57d8e052126715492
  So I will only readd -ffloat-store if people request it, and even
  then, only to specific parts of code and not everything.
* Fix src/3rdparty/chromium/third_party/WebKit/Source/platform/audio/
  DirectConvolver.cpp to not require SSE2 on x86. (No runtime detection,
  sorry.)
* Update the changelog date in the specfile.

Do not require SSE2 on i686

See https://bugzilla.redhat.com/show_bug.cgi?id=1244196#c22 for the
history of the patch. Compared to the last revision there (v5):
* I fixed WebGLImageConversion.cpp to not assume SSE2 on x86.
  Unfortunately, it would be really hard to make runtime detection work
  there, because it uses intrinsics in inline templates, and GCC only
  supports intrinsics when building the whole code for the vector
  instruction set. So I had to turn off that SSE2 code entirely when
  __SSE2__ is not defined at compile time.
* I fixed webrtc to check for SSE2 at runtime (using the runtime
  checking code that webrtc already has and uses in several places)
  before attempting to use OpenMAX on x86. OpenMAX requires SSE2.
  So we just fall back to the Ooura implementation of FFTs when needed.
