Just having --implicit-check-not=/usr breaks when the LLVM checkout path
contains '/usr', since llvm-objdump prints out the path to the input
file in the first line. Tighten the checks by adding the 'name' prefix
that's used when printing load command payloads. An alternative would be
to redirect the input file into llvm-objdump, in which case it prints
out 'a.out' as the file name, but I'm not sure how reliable that
behavior is.
Implement `-id` option for install-name-tool. Differences from cctool's
behavior:
- Does **NOT** throw an error if multiple -id options are specified.
Instead, picks the last one.
- Throws an error in case empty id is specified.
