perf arm-spe: Fix load-store operation checking
[ Upstream commit e1d47850bbf79a541c9b3bacdd562f5e0112274d ]
The ARM_SPE_OP_LD and ARM_SPE_OP_ST operations are secondary operation
type, they are overlapping with other second level's operation types
belonging to SVE and branch operations. As a result, a non load-store
operation can be parsed for data source and memory sample.
To fix the issue, this commit introduces a is_ldst_op() macro for
checking LDST operation, and apply the checking when synthesize data
source and memory samples.
