Fangrui Song abe0dd195a [llvm-objdump] Print ... even if a data mapping symbol is active
Swap `!DisassembleZeroes` and `if (DumpARMELFData)` conditions so that
in the false DisassembleZeroes case (default), `...` will be printed for
long consecutive zeroes, even when a data mapping symbol is active.

This is especially useful for certain lld tests that insert a huge
padding within a code section. Without `...` the output will be huge.
