This test was failing because it was checking that eax was being cleared. For
sysv abi, eax contains the number of XMM registers used in the call, but msabi
just passes the float arguments twice, both in xmm and general purpose
registers.
This patch adds tests for both sysv and msabi functions being called, and adds
some more tests that check for for argument being placed in the correct
register.
Tested on x86_64-linux-gnu and x86_64-w64-mingw32

* gcc.target/i386/amd64-abi-9.c: Add sysv attribute to called function
Add msabi attribute function
Add test checking parameter is placed in correct register
