[PATCH 0/2] AArch64 AAPCS: Improve argument passing

[Alan Hayward <Alan.Hayward@arm.com>]

This series improves the AAPCS argument passing on AArch64 (where small
structures are passed via float registers instead of on the stack).

The first patch ensures empty structures in C++ are dealt with correctly.
The second deals with static struct members.

It replaces the patch
"AArch64: Prevent infinite recursion when checking AAPCS types",
as the test failure is covered by the above. However that patch may still
be required in the future if I can craft a valid test case for it.

This patch adds a new test and expands an exisiting test. When run on
x86_64, many of the new test cases fail with:
amd64-tdep.c:958: internal-error: CORE_ADDR amd64_push_arguments(regcache*,
int, value**, CORE_ADDR, function_call_return_method): Assertion
`!"Unexpected register class."' failed
I had a look, but I don't know enough about the x86 argument passing.

Alan.
