Issue 42002: Breakpad DWARF parser: avoid using <stdint.h> type

It seems that a use of the <stdint.h> type uintptr_t has crept into
the DWARF parser. This defines a workaround for the GNU compilers
(tested on both Mac and Linux) which will raise an error if it doesn't
work.

My personal preference would be just to assume that the <stdint.h>
header is available and use the standard types everywhere, but 1) that
would be a large change, likely to make merges with the other branches
of the DWARF parser more difficult, and 2) it would make it quite
difficult to build under Microsoft Visual Studio, which doesn't have
the <stdint.h> header; Microsoft has said they have no plans to
provide it, as they would rather "focus their efforts" on C++ and
.NET.
