This is likely going to be very controversial. It's going to increase the
size of two of most heavily used data structures in GCC (rtx and trees).
The first thing I would ask is whether or not we really need the full matrix
in practice or if we can combine some of the modes.
Why hasn't aarch64 stumbled over this problem?
From what I can see, x86 has 130 modes and aarch64 178 right now.
To put it another way. Why does RISC-V have so many more modes than
AArch64.
