[patch, ARM] Fix PR45447

[Yao Qi]

We created a struct type for va_list to follow ARM ABI, but TREE_CHAIN
(va_list_type) is *not* set properly.  This problem causes segmentation
fault reported in PR45447.

This patch is to address this problem.  Regression test for
arm-none-linux-gnueabi is still running.  OK to trunk/4.5/4.4 if no
regression?
