arm: [MVE intrinsics] add mode_after_pred helper in function_shape
This new helper returns true if the mode suffix goes after the
predicate suffix. This is true in most cases, so the base
implementations in nonoverloaded_base and overloaded_base return true.
For instance: vaddq_m_n_s32.
This will be useful in later patches to implement
vstr?q_scatter_offset_p (_p appears after _offset).
gcc/ChangeLog:
* config/arm/arm-mve-builtins-shapes.cc (struct
nonoverloaded_base): Implement mode_after_pred.
(struct overloaded_base): Likewise.
* config/arm/arm-mve-builtins.cc (function_builder::get_name):
Call mode_after_pred as needed.
* config/arm/arm-mve-builtins.h (function_shape): Add
mode_after_pred.
