[Bug middle-end/36791] New: ICE with constant argument to __builtin_eh_return

[jfc at mit dot edu]

This function causes an ICE in rtl generation:

void g()
{
  __builtin_eh_return(0, 0);
}

The crash happens when either operand to __builtin_eh_return is an integer
constant.  expand_builtin_eh_return calls copy_to_reg on a CONST_INT operand. 
copy_to_reg generates a register with mode VOIDmode.

I think the fix is to change the two calls to copy_to_reg to copy_addr_to_reg
in expand_builtin_eh_return.

This bug seems to be present for many versions and on at least two targets, x86
and SPARC.

Note that with optimization on the same crash may occur if a variable known to
hold an integer constant value is passed as the first argument.

This is a dup of bug 67619 which is fixed in GCC 4.9.4, GCC 5.3.0, and GCC 6+
