Wentao Guan ea6e650b07 arm64/scs: Fix potential sign extension issue of advance_loc4 ...

[ Upstream commit 4023b7424e ]

The expression (*opcode++ << 24) and exp * code_alignment_factor
may overflow signed int and becomes negative.

Fix this by casting each byte to u64 before shifting. Also fix
the misaligned break statement while we are here.

Example of the result can be seen here:
Link: https://godbolt.org/z/zhY8d3595

It maybe not a real problem, but could be a issue in future.
