lld seems to not zero flags for binary inputs for Hexagon, Arm, AArch64 either so that should be ok |

Please zero the flags for all architectures, it does not make sense to not have the flags 0'ed for specific architectures.
$arm-none-eabi-ld.bfd -marmelf --format=binary mydata.blob -o mydata.elf && llvm-readelf -h mydata.elf | grep Flags
Flags: 0x0
$aarch64-linux-gnu-ld.bfd -maarch64elf --format=binary mydata.blob -o mydata.elf && llvm-readelf -h mydata.elf | grep Flags
Flags: 0x0
Please compare bfd behavior at all times

Instead of creating seperate commits this way, I would appreciate if you could seperate each target specific change to a seperate commit or a PR.
Combining all of them together is making it hard to review.
Binary files have no architecture flags, so the default value of -1 is used instead of 0. Also removes unused code in TargetInfo.h Signed-off-by: quic-areg <aregmi@quicinc.com>
