[PATCH][ARM][1/3] Add vectorization support for rounding functions

["Kyrylo Tkachov" <kyrylo dot tkachov at arm dot com>]

Hi all,

This patch does some refactoring by moving the definitions of the NEON
builtins to a separate file (arm_neon_builtins.def) and includes that when
initialising the neon_builtin_data array and also during
the definition of enum arm_builtins (with appropriate redefinitions of the
VAR* macros). This allows us to have symbolic names for the neon builtins
that allows us to look up their declaration in
arm_builtin_decls. This is needed for vectorisation support in the next
patch. The ARM_BUILTIN_NEON_BASE constant which was defined as part of the
arm_builtins enum is now defined as a macro, since
various functions that deal with the initialisation and expansion of
builtins use it.

No regressions on arm-none-eabi with model.

Ok for trunk?

Thanks,
Kyrill
