i386: Avoid =&r,r,r andn double-word alternative for ia32 [PR114810]

Hi!

As discussed in the PR, on ia32 with its 8 GPRs, where 1 is always fixed
and other 2 often are as well having an alternative which needs 3
double-word registers is just too much for RA.
The following patch splits that alternative into two, one with o is used
even on ia32, but one with the 3x r is used just for -m64/-mx32.
Tried to reduce the testcase further, but it wasn't easily possible.

Bootstrapped/regtested on x86_64-linux and i686-linux, ok for trunk?

	PR target/114810
	* config/i386/i386.md (*andn<dwi>3_doubleword_bmi): Split the =&r,r,ro
	alternative into =&r,r,r enabled only for x64 and =&r,r,o.

	* g++.target/i386/pr114810.C: New test.
