[Matrix] Support #pragma clang fp
From https://bugs.llvm.org/show_bug.cgi?id=49739:
Currently, `#pragma clang fp` are ignored for matrix types.
For the code below, the `contract` fast-math flag should be added to the generated call to `llvm.matrix.multiply` and `fadd`
```
typedef float fx2x2_t __attribute__((matrix_type(2, 2)));
void foo(fx2x2_t &A, fx2x2_t &C, fx2x2_t &B) {
#pragma clang fp contract(fast)
C = A*B + C;
}
```
