Can you make this <code>RDSEED</code>, <code>... and so forth?
(This is a bit borderline, in that one could also see this as
more general references, but usually we mark those up.)
And "...through the ... command-line options."?

"the ... intrinsics" (and same below for "instruction sets")
+ <li> x86 backend was improved to allow option
<code>-fscedule-insns</code> to work reliably.
"The x86 backend has been improved..."
+ This option can be used to schedule instructions better and can
lead to improved performace in certain cases.
This line is quite long, can you break lines around 76 columns?
And, let's be a bit more brave and omit either "can" or "in certain
cases". Otherwise this may sounds too unlikely. :-)
The patch is fine with changes along the lines described above.
