55c19060a6 [libFuzzer] Portably disassemble and find calls to sanitizer_cov_trace_pc_guard.
Instead of directly using objdump, which is not present on Windows, we consider
different tools depending on the platform.
For Windows, we consider dumpbin and llvm-objdump.

f51c50474c [libFuzzer] Clean up headers and file formatting of LibFuzzer files.
Reorganize #includes to follow LLVM Coding Standards.
Include some missing headers. Required to use `Printf()`.

Aside from that, this patch contains no functional change.
It is purely a re-organization.

0ca1e73f19 [libFuzzer] Properly use unsigned for Process ID.
Use unsigned for PID instead of signed int. GetCurrentProcessId() returns
an unsigned (DWORD) so we must be sure we can deal with all possible values.
I use a long unsigned to be sure it can hold a 32 bit unsigned (DWORD).

9fb21ea4f5 [libFuzzer] Improve Signal Handler interface.
Add new flags to FuzzingOptions to represent the different conditions
on the signal handling. These options are passed when calling
SetSignalHandler().
This changes simplify the implementation of Windows's exception
handling. Now we can define a unique handler for all the exceptions.

1a45ade2ce Resubmit "[LibFuzzer] Split FuzzerUtil for Posix and Windows."
This resubmits r288529, which was resubmitted because it broke a
fuzzer bot.  According to kcc@ the test that broke was flakey
and it is unlikely to be a result of this patch.

This reverts commit r288529, as it seems to introduce some
problems on the Linux bots.
