source (I.E. leftmost dimension first, next to leftmost second,
etc).
The data items describing each array dimension consist of four
parts: (1) a format specifier, (2) type type of the subscript
index, (3) a description of the low bound of the array dimension,
and (4) a description of the high bound of the array dimension.
The last data item is the description of the type of each of
the array elements.
We are passed a pointer to the start of the block of bytes
containing the data items, and a pointer to the first byte past
the data. This function decodes the data and returns a type.
containing the remaining data items, and a pointer to the first
byte past the data. This function recursively decodes the

If we somehow fail to decode some data, we complain about it
and return a type "array of int".

NOTES
If we encounter a fundamental type that we are unprepared to

treat the type as an "int".
For robustness, if we are asked to translate a fundamental
type that we are unprepared to deal with, we return int so
callers can always depend upon a valid type being returned,
and so gdb may at least do something reasonable by default.
If the type is not in the range of those types defined as
