perf annotate: Do not truncate instruction names at 6 chars

Browse Source 
There are many instructions, esp on PowerPC, whose mnemonics are longer
than 6 characters. Using precision limit causes truncation of such
mnemonics.

Fix this by removing precision limit. Note that, 'width' is still 6, so
alignment won't get affected for length <= 6.

Before:

   li     r11,-1
   xscvdp vs1,vs1
   add.   r10,r10,r11

After:

  li     r11,-1
  xscvdpsxds vs1,vs1
  add.   r10,r10,r11
