Fixes a data race due to multiple dr_standalone_init() done in parallel (per shard) by encodings2regdeps_filter_t. dcontext is now initialize one time by record_filter_t and passed to its filters through the record_filter_info_t interface. Issue #6662
is expected in dcontext_t initialization when running record_filter_launcher.
DR_ISA_REGDEPS in opcode_mix dcontext.
data race when we read the dcontext isa_mode in decode().

Fixes a data race due to multiple dr_standalone_init() done in parallel (per shard) by encodings2regdeps_filter_t.
dcontext is now initialized one time by record_filter_t and passed to its filters through the record_filter_info_t interface.
Avoids a data race in opcode_mix where all threads set the dcontext isa_mode to DR_ISA_REGDEPS for regdeps input traces.
