perf annotate: Do not ignore call instruction with indirect target
Do not ignore call instruction with indirect target when its already
identified as a call. This is an extension of commit e8ea1561952b ("perf
annotate: Use raw form for register indirect call instructions") to
generalize annotation for all instructions with indirect calls.
This is needed for certain powerpc call instructions that use address in
a register (such as bctrl, btarl, ...).
Apart from that, when kcore is used to disassemble function, all call
instructions were ignored. This patch will fix it as a side effect by
not ignoring them. For example,
Before (with kcore):
mov %r13,%rdi
callq 0xffffffff811a7e70
^ jmpq 64
mov %gs:0x7ef41a6e(%rip),%al
After (with kcore):
mov %r13,%rdi
> callq 0xffffffff811a7e70
^ jmpq 64
mov %gs:0x7ef41a6e(%rip),%al

[Suggested about 'bctrl' instruction]
