Certain minidumps for 32-bit crashes have the upper 32-bit of the crash
address (which is a 64-bit value) set to non-zero values. This caused a
crash address with more than 32-bits to be printed out for minidumps of
32-bit architectures. This patch masks out those bits when reading the
raw minidump data to ensure this doesn't happen anymore.

This affects the output of tools like minidump_stackwalk which currently
print out the hexadecimal representation of the architecture instead of
the "arm64" string.

Eventually, I want to remove the current version of
SetFirstChanceHandler. That is why I changed the name of the current
callback type to FirstChanceHandlerDeprecated.
I also made sure that it is not possible to have two different
FirstChanceHandlers set at the same time.
This is the first of a set of CLs to clean up the API between Chrome,
BreakPad, and V8. See more information in the tracking bug.

This enables the DWARF reader to properly parse DW_AT_ranges attributes
in compilation units and functions. Code covered by a function is now
represented by a vector of ranges instead of a single contiguous range
and DW_AT_ranges entries are used to populate it. All the code and tests
that assumed functions to be contiguous entities has been updated to
reflect the change. DW_AT_ranges attributes found in compilation units
are parsed but no data is generated for them as it is not currently needed.

This struct matches the layout defined by Microsoft and replaces
Breakpad's MDRawContextARM64_Old. This CL updates the processor to
understand either the old or new structs, but clients continue to write
the old structs.

When DW_AT_MIPS_linkage_name doesn't demangle, breakpad currently throws
the symbol completely, but in some cases, there is no DW_AT_name or
DW_AT_abstract_origin to figure out a name, and the raw value from
DW_AT_MIPS_linkage_name is still better than nothing. Fall back to that
in when there is nothing else.

for being too long.
We've seen some minidumps that fail to process because they contain
a ridiculous number of modules (usually due to something leaking shm
mappings, it looks like). They're annoying to investigate because even
minidump_dump fails to load and print the module list. This patch makes
minidump_dump effectively remove the limit on the number of modules it
will load, so inspecting the dump by hand is possible.
