*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

return NULL for an invalid register.
The unwind logic asks for the "return address register" which doesn't exist
on x86/x86_64, returns -1 and calls this with -1 as a parameter, ends up
out of scope of the array bounds for g_register_infos and later SIGSEGVs
on accessing. This now matches the other GetRegisterInfoAtIndex for
other platforms.

In some circumstances (notably, certain minidumps), the thread CONTEXT does not have values for the
control registers (EIP, ESP, EBP, EFLAGS). There are flags in the CONTEXT which indicate which
portions are valid, but those flags weren't checked. The old code would not detect this and give a
garbage value for the register. The new code will log the problem and return an error.
I consolidated the error checking and logging into a helper function, which makes the big switch
statement easier to read and verify.
Ran tests to ensure this doesn't break anything. Manually verified that a minidump without info on
the control registers now indicates the problem instead of giving bad information.
