Fixed counters can also generate adaptive PEBS record, if the
corresponding bit in IA32_FIXED_CTR_CTRL is set.
Otherwise, only basic record is generated.

corresponding bit in IA32_FIXED_CTR_CTRL is set.
Otherwise, only basic record is generated.
Unconditionally set the bit when PEBS is enabled on fixed counters.
Let MSR_PEBS_CFG decide which format of PEBS record
