Make sure CodeView symbols are aligned

CodeView symbols have to be multiples of four bytes; add an alignment
directive to write_data_symbol to ensure this.

Note that these can be zeroes, so we can rely on GAS to do this for us;
it's only types that need f3, f2, f1 values.

gcc/
	* dwarf2codeview.cc (write_data_symbol): Add alignment directive.
