perf annotate: Do not truncate instruction names at 6 chars
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
