This diff required fixing `getEmbeddedAddend` to apply sign
extension to 32-bit values. We were previously passing around wrong
64-bit addend values that became "right" after being truncated back to
32-bit.
I've also made `getEmbeddedAddend` return a signed int, which is similar
to what LLD-ELF does for its `getImplicitAddend`.
`reportRangeError`, `checkUInt`, and `checkInt` are counterparts of similar
functions in LLD-ELF.
