If the referenced symbol of a J[U]MP_SLOT is invalid (e.g. symbol index 0), llvm-objdump -d will bail out: ``` error: 'a': st_name (0x326600) is past the end of the string table of size 0x7 ``` where 0x326600 is the st_name field of the first entry past the end of .symtab Change it to a warning to continue dumping. `X86/plt.test` uses a prebuilt executable, so I pick `ELF/AArch64/plt.test` which has a YAML input and can be easily modified.

// These test checks that llvm-objdump will not crash with malformed Mach-O

// make sure llvm-objdump is robust is what matters.
