Accept code attributes as rtx codes in .md files
The recent AArch64 absolute difference patterns had to go through
some hoops to pair max/min rtx codes with the same signedness.
I also need to pair signed/unsigned codes with sign/zero extension
for some SVE ACLE patterns.
This patch therefore supports <...> as rtx codes, like we already
do for modes.
