benchmarks for bionic

[unicornx]

we need code analysis on benchmarks for bionic (code are mostly under bionic/benchmarks), understand what it is doing and how it implement the benchmark. output required:

• a code-analysis report (in text )to clarify what the benchmark is doing and what's the design of this module. We need to review this. After it is ok, a speech report is required (please provide a slides, and a video recording is fine if you can not provide it on line).

• fix an unsolved FIXEME in bionic/benchmarks/linker_relocation/include/linker_reloc_bench_asm.h, resolve it and run the benchmark and get the test result.

  #elif defined(__riscv) && (__riscv_xlen == 64)
  
  // FIXME: have not tested it out, is it ok?
  #define GOT_RELOC(sym) auipc a0, %got_pcrel_hi(sym)
  #define CALL(sym) call sym@plt
  #define DATA_WORD(val) .quad val
  #define MAIN .globl main; main: nop; ret
