* alpha-tdep.h (gdbarch_tdep): Add vm_min_address member.
* alpha-tdep.c (heuristic_proc_start): Use vm_min_address
from gdbarch_tdep rather than a constant.
(alpha_gdbarch_init): Initialize tdep->vm_min_address to
the default text address for all Alpha Unix ABIs.
(alpha_dump_tdep): Report the value of tdep->vm_min_address.
* config/alpha/tm-alpha.h (VM_MIN_ADDRESS): Delete.
