Mark various tests that require a c99 libm

Browse source 
A number of i386 math optimisation tests are looking assembly instructions
that are only emitted when the compiler knows the target has a C99 libm
available. Since targets like *-elf may not have such a libm, a C99 runtime
requirement is added to these tests.
