alpha.c (struct machine_function): New flag for VMS, uses_condition_handler.
* config/alpha/alpha.c (struct machine_function): New flag for VMS,
uses_condition_handler.
(alpha_expand_builtin_establish_vms_condition_handler): New expander.
(alpha_expand_builtin_revert_vms_condition_handler): New expander.
(enum alpha_builtin): New ALPHA_BUILTIN_REVERT_VMS_CONDITION_HANDLER
and ALPHA_BUILTIN_ESTABLISH_VMS_CONDITION_HANDLER values.
(code_for_builtin): New insn codes for the new alpha_builtins.
(alpha_init_builtins): Register the new functions as BUILT_IN_MD.
(alpha_sa_size): Account for uses_condition_handler.
(alpha_expand_prologue): Likewise.
(alpha_start_function): Likewise.
(alpha_expand_epilogue): Likewise.
* config/alpha/alpha-protos.h: Prototype the new alpha.c builtin
establish/revert expanders.

* config/alpha/alpha.md (builtin_establish_vms_condition_handler):
New expander, resorting to the alpha.c associated function.
(builtin_revert_vms_condition_handler): Likewise.
* config/alpha/vms-gcc_shell_handler.c: New file. Implements
__gcc_shell_handler, the static VMS condition handler used as
an indirection wrapper to the current dynamically established
handler.
