vms: Replace use of LONG_DOUBLE_TYPE_SIZE
Joseph pointed out "floating types should have their mode,
not a poorly defined precision value" in the discussion[1],
as he and Richi suggested, the existing macros
{FLOAT,{,LONG_}DOUBLE}_TYPE_SIZE will be replaced with a
hook mode_for_floating_type. To be prepared for that, this
patch is to replace use of LONG_DOUBLE_TYPE_SIZE in vms port
with TYPE_PRECISION of long_double_type_node.

gcc/ChangeLog:
* config/vms/vms.cc (vms_patch_builtins): Use TYPE_PRECISION of
long_double_type_node to replace LONG_DOUBLE_TYPE_SIZE.
