jasonliu d5143e3f10 Remove '<' from test for better yam2obj input consumption 
Address post-commit comment:
https://reviews.llvm.org/D77580#inline-713676

yaml2obj does not record the source filename in the output,
 which may make FileCheck tests brittle sometimes.

Fangrui Song 7f36cb1f1a [AArch64InstPrinter] Change printAlignedLabel to print the target address in hexadecimal form 
Similar to D76580 (x86) and D76591 (PPC).

```
// llvm-objdump -d output (before)
10000: 08 00 00 94                   bl      #32
10004: 08 00 00 94                   bl      #32

// llvm-objdump -d output (after)
10000: 08 00 00 94                   bl      0x10020
10004: 08 00 00 94                   bl      0x10024

// GNU objdump -d. The lack of 0x is not ideal due to ambiguity.
10000:       94000008        bl      10020 <bar+0x18>
10004:       94000008        bl      10024 <bar+0x1c>
```

The new output makes it easier to find the jump target.

Fangrui Song 87de9a0786 [X86InstPrinter] Change printPCRelImm to print the target address in hexadecimal form 
```
// llvm-objdump -d output (before)
400000: e8 0b 00 00 00   callq 11
400005: e8 0b 00 00 00   callq 11

// llvm-objdump -d output (after)
400000: e8 0b 00 00 00  callq 0x400010
400005: e8 0b 00 00 00  callq 0x400015

// GNU objdump -d. The lack of 0x is not ideal because the result cannot be re-assembled
400000: e8 0b 00 00 00  callq 400010
400005: e8 0b 00 00 00  callq 400015
```

In llvm-objdump, we pass the address of the next MCInst. Ideally we
should just thread the address of the current address, unfortunately we
cannot call X86MCCodeEmitter::encodeInstruction (X86MCCodeEmitter
requires MCInstrInfo and MCContext) to get the length of the MCInst.

MCInstPrinter::printInst has other callers (e.g llvm-mc -filetype=asm, llvm-mca) which set Address to 0.
They leave MCInstPrinter::PrintBranchImmAsAddress as false and this change is a no-op for them.

Fangrui Song ecd6d7254e [test] llvm/test/: change llvm-objdump single-dash long options to double-dash options 
As announced here: http://lists.llvm.org/pipermail/llvm-dev/2019-April/131786.html

Grouped option syntax (POSIX Utility Conventions) does not play well with -long-option
A subsequent change will reject -long-option.
