[PATCH]] PR target/81084: Fork documentation for powerpcspe and clean up

[Andrew Jenner <andrew at codesourcery dot com>]

This patch adds a section to invoke.texi for the new PowerPC SPE 
backend, mostly copied from the PowerPC backend but with irrelevant 
options removed.

The patch also removes documentation of the SPE-specific options -mspe, 
-mno-spe and -mfloat-gprs from the PowerPC backend (these options have 
already been removed from the PowerPC backend's code).

As per the PR, I did look in install.texi to see if there were any 
similar changes that I should make there, but to me that file looks okay 
for now.

I have built GCC with these changes and inspected the generated html 
files which look fine to me.

Okay to commit to trunk?

Thanks,

Andrew
