This patch passes `uint64_t Address` to print methods of PC-relative
operands so that subsequent target specific patches can change
`*InstPrinter::print{Operand,PCRelImm,...}` to customize the output.
Add MCInstPrinter::PrintBranchImmAsAddress which is set to true by
llvm-objdump.
```
// Current llvm-objdump -d output
aarch64: 20000: bl #0
ppc: 20000: bl .+4
x86: 20000: callq 0
// Ideal output
aarch64: 20000: bl 0x20000
ppc: 20000: bl 0x20004
x86: 20000: callq 0x20005
// GNU objdump -d. The lack of 0x is not ideal because the result cannot be re-assembled
aarch64: 20000: bl 20000
ppc: 20000: bl 0x20004
x86: 20000: callq 20005
```
In `lib/Target/X86/X86GenAsmWriter1.inc` (generated by `llvm-tblgen -gen-asm-writer`):
```
case 12:
// CALL64pcrel32, CALLpcrel16, CALLpcrel32, EH_SjLj_Setup, JCXZ, JECXZ, J...
- printPCRelImm(MI, 0, O);
+ printPCRelImm(MI, Address, 0, O);
return;
```
Some targets have 2 `printOperand` overloads, one without `Address` and
one with `Address`. They should annotate derived `Operand` properly with
`let OperandType = "OPERAND_PCREL"`.
