[AIX] Update data directives for AIX assembly 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.

[XCOFF][AIX] Use 'L..' instead of 'L' for PrivateGlobalPrefix Without this change, names start with 'L' will get created as temporary symbol in MCContext::createSymbol. Some other potential prefix considered: .L, does not work for AIX, as a function start with L will end up with .L as prefix for its function entry point. ..L could work, but it does not play well with the convention on AIX that anything start with '.' are considered as entry point. L. could work, but not sure if it's safe enough, as it's possible to have suffixes like .something append to a plain L, giving L.something which is not necessarily a temporary. That's why we picked L.. for now. Differential Revision: https://reviews.llvm.org/D80831
