[Patch,testsuite] Fix tests that fail due to symbol visibility when -fPIC

[Vidya Praveen]

Hello,

The following  test cases fail when -fPIC  is passed  as dejagnu multilib flag 
since -fPIC  causes the  'availability' of the functions to be overwritable. I 
have fixed this by adding bind_pic_locally to these cases.

  gcc.dg/fail_always_inline.c
  gcc.dg/inline-22.c
  gcc.dg/inline_4.c
  g++.dg/ipa/devirt-25.C

Tested on:

  aarch64-none-elf
  aarch64-none-linux-gnu
  arm-none-linux-gnueabihf
  x86_64-unknown-linux-gnu

OK for trunk?

Cheers
VP.
