Currently minimal alignment of function is hardcoded to 2 bytes. Add 2 more cases: 1. In case BF is data in code return the alignment of CI as minimal alignment 2. For aarch64 and riscv platforms return the minimal value of 4 (added test for aarch64) Otherwise fallback to returning the 2 as it previously was.

// This tests checks the minimum alignment of the AARch64 function
|
|
// is equal to 4. Otherwise the jitlinker would fail to link the
|
|
// binary since the size of the first function after reorder is not
|
|
// not a multiple of 4.
