William Cohen 0ba37e05c2 perf annotate: Add riscv64 support 
This patch adds basic arch initialization and instruction associate
support for the riscv64 CPU architecture.

Example output:

  $ perf annotate --stdio2
  Samples: 122K of event 'task-clock:u', 4000 Hz, Event count (approx.): 30637250000, [percent: local period]
  strcmp() /usr/lib64/libc-2.32.so
  Percent

	      Disassembly of section .text:

	      0000000000069a30 <strcmp>:
	      __GI_strcmp():
	      const unsigned char *s2 = (const unsigned char *) p2;
	      unsigned char c1, c2;

	      do
	      {
	      c1 = (unsigned char) *s1++;

	      c2 = (unsigned char) *s2++;

   18.68        addi a0,a0,1
	      c2 = (unsigned char) *s2++;
    1.37        lbu  a4,-1(a1)
	      if (c1 == '\0')
   18.71      ↓ beqz a5,18
	       return c1 - c2;
	       }
