Yi Kong 9825a6c7f8 afdo: Remove -fprofile-sample-accurate flag
-fprofile-sample-accurate allows the compiler to de-optimize cold code
paths according to the profile. However we have a number of micro-
benchmarks that tests these paths and we often trigger regression
reports from those benchmarks.

Turning off the flag mitigates the issue at a cost of ~2MB increase in
system image size. But the more deterministic codegen could reduce the
differential OTA size.

Test: presubmit
