[PATCH 0/3] MR1091: Support block spreading across multiple address ranges.

[eric pouech (＠epo)]

This series improves support for blocks which spread across several
non contiguous memory chunks.

Mingw/Gcc tends to emit quite a few of these, especially in 32bit mode.
Now the gaps (between two valid ranges) will no longer be understood
as being part of the block, hence potentially hiding valid information
lying in other blocks.

Note that native doesn't support blocks with multiple ranges of addresses
(MSVC stores the information quite differently), so these ranges will
be used internally but not exposed to DbgHelp's user.
