[AIX][XCOFF]Implement mergeable const SUMMARY: In this patch, we map mergeable const objects to the read-only section in the same manner as const objects that are not mergeable.

; This file tests the codegen of mergeable const in AIX assembly.
; This file also tests mergeable const in XCOFF object file generation.
[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.
