Igor Sheludko 8a56da4459 [builtins][masm] Move hot flags to the beginning of IsolateData 
... so that the offset fits into the maximum offset for load byte
instruction for arm/arm64 (Ldrb) in order to produce smaller code.

Update code generation so that the loading of the flag value is
combined with the comparison operation where possible.

Additionally, this CL moves the Isolate::is_profiling flag to the
IsolateData so that it can be loaded directly via roots register which
removes one indirection.

The fields moved in the IsolateData:
 - is_marking_flag and is_minor_marking_flag (checked by write barriers)
 - is_profiling (checked on API callbacks/getter calls)
 - stack_is_iterable (not super hot, checked during deoptimization).

Drive-by: this CL defines the bool fields as uint8_t in order to make
the field size expectations clear.
