swift: add auto increase frame size

[eladciuraru]

sometimes in swift code, when there is a code that runs a closure on dispatch queue,
it dynamically allocates on the stack as can seen below:

MOV             X8, SP
SUB             X2, X8, #0x30 ; '0' ; params
MOV             SP, X2
...
BL              _$sSo17OS_dispatch_queueC8DispatchE4sync5flags7executexAC0D13WorkItemFlagsV_xyKXEtKlF ; OS_dispatch_queue.sync<A>(flags:execute:)

IDA does not recognize this and when looking at the disassembly,
it looks like it tries to access negative offsets:

    *(_QWORD *)&v12[-32] = v9;
    *(Swift::String *)&v12[-24] = v8;
    OS_dispatch_queue.sync<A>(flags:execute:)(
      &type metadata for (),
      v10,
      (int)v7,
      sub_100033624,
      &v12[-48],
      &type metadata for () + 1);
    (*(void (__fastcall **)(_BYTE *, __int64))(v5 + 8))(v7, v4);

to be able to manually define a struct there you first need to manually edit the function
and increase the frame size.

this commit introduces a simple solution to automatically increase the frame size
in case of finding this pattern, it is not a good solution but it gets the job done when needed. let me know what do you think of this.
