Summary: The standard data emission directives (e.g. .short, .long) in the AIX assembler have the unintended consequence of aligning their output to the natural byte boundary. This cause problems because we aren't expecting behavior from the Data*bitsDirectives, so the final alignment of data isn't correct in some cases on AIX. This patch updated the Data*bitsDirectives to use .vbyte pseudo-ops instead to emit the data, since we will emit the .align directives as needed. We update the existing testcases and add a test for emission of struct data.
