On some targets (ia32 for an example), sizeof long double
is not a power of 2, this means you can't create a vector
of it. So let's disable this testcase for non power of 2
sizeof long double. This needs to be done via a preprocessor
macro as vector_size would cause an error otherwise.
Committed as obvious after a test on x86_64 with -m32.
gcc/testsuite/ChangeLog:
* c-c++-common/torture/pr124086-1.c: Only enable
for power of 2 long double.
