Add three new builtin types (builtin_type_long_double, builtin_type_complex,

and builtin_type_double_complex).  Also add and use various TARGET_<TYPE>_BIT
macros to indicate the sizes of various types on the target machine.

+       * c-exp.y, defs.h, symtab.h, valprint.c:  Add three new builtin
+       types to gdb, builtin_type_long_double, builtin_type_complex, and
+       builtin_type_double_complex.  Add and use new TARGET_SHORT_BIT,
+       TARGET_INT_BIT, TARGET_LONG_BIT, TARGET_FLOAT_BIT,
+       TARGET_DOUBLE_BIT, TARGET_LONG_DOUBLE_BIT, TARGET_COMPLEX_BIT, and
+       TARGET_DOUBLE_COMPLEX_BIT, as the sizes in bits of the indicated
+       types on the target machine (ala the existing TARGET_LONG_LONG_BIT).
+
        * infrun.c:  When using SVR4 /proc interface instead of ptrace(),
        call proc_set_exec_trap() to setup child to stop at first instruction.
