gdb/alpha: Add target description support

This commit adds target description support for Alpha.

The target description obviates the alpha_register_type and
alpha_register_name functions in alpha-tdep.c. Removal of
alpha_register_reggroup_p was considered but ultimately abandoned,
because the "info regs" command would no longer omit the zero, fpcr, and
unique registers from its output (they are neither vector nor float
types).

Register types in the target description annex match the types that the
alpha_register_type function returned.

The locally defined register_names array was moved out of
alpha_register_name and renamed to alpha_register_names as a static
global; calls to alpha_register_name have been replaced with direct
access of the array.

The patch follows the code pattern outlined in the following GDB
Internals Wiki entry:
