This removes EImode from the (AArch64) compiler, and all mention of or support
for it.
bootstrapped and check-gcc on aarch64-none-linux-gnu
gcc/ChangeLog:
* config/aarch64/aarch64.c (aarch64_simd_attr_length_rglist): Update
comment.
* config/aarch64/aarch64-builtins.c (ei_UP,
aarch64_simd_intEI_type_node): Remove.
(aarch64_simd_builtin_std_type): Remove EImode case.
(aarch64_init_simd_builtin_types): Don't create/add intEI_type_node.
* config/aarch64/aarch64-modes.def: Remove EImode.
