[gdb/tdep] Fix PowerPC IEEE 128-bit format arg passing
On a powerpc system with gcc 12 built to default to 128-bit IEEE long double,
I run into:
...
(gdb) print find_max_long_double_real(4, ldc1, ldc2, ldc3, ldc4)^M
$8 = 0 + 0i^M
(gdb) FAIL: gdb.base/varargs.exp: print \
find_max_long_double_real(4, ldc1, ldc2, ldc3, ldc4)
...
This is due to incorrect handling of the argument in ppc64_sysv_abi_push_param.
Fix this and similar cases, and expand the test-case to test handling of
homogeneous aggregates.
Tested on ppc64le-linux, power 10.
