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.

To be consistent with other directives like '.comm', '.lcomm', we remove
the spaces after the comma for '.csect' on AIX.

Summary:
This patch tries to emit the correct alignment result for both
object file generation path and assembly path.

SUMMARY:
We currently emit a reference for function address constants as labels;
for example:
foo_ptr:
.long foo
however, there may be no such label in the case where the function is
undefined. Although the label exists when the function is defined, we
will (to be consistent) also use a csect reference in that case.
