Avoid double profile udpate in try_peel_loop
try_peel_loop uses gimple_duplicate_loop_body_to_header_edge which subtracts the profile
from the original loop. However then it tries to scale the profile in a wrong way
(it forces header count to be entry count).
This eliminates to profile misupdates in the internal loop of sphinx3.
