  1. Handle va_arg on struct types for the le32 target (PNaCl and Emscripten) 

    Cherry picked from https://codereview.chromium.org/183973037, itself a
cherry pick from clang upstream r199830, originally
authored by mseaborn@chromium.org

PNaCl and Emscripten can both handle va_arg IR instructions with
struct type.

Also add a test to cover generating a va_arg IR instruction from
va_arg in C on le32 (as already handled by VisitVAArgExpr() in
CGExprScalar.cpp), which was not covered by a test before.
