[sanitizer] Make atos stdin a non-tty pipe to make sure it's not stuck waiting for user input
On macOS, we often symbolicate using atos (when llvm-symbolizer is not found). The current way we invoke atos involves creating a pseudo-terminal to make sure atos doesn't buffer its output. This however also makes atos think that it's stdin is interactive and in some error situations it will ask the user to enter some input instead of just printing out an error message. For example, when Developer Mode isn't enabled on a machine, atos cannot examine processes, and it will ask the user to enter an administrator's password, which will make the sanitized process get stuck. This patch only connects the pseudo-terminal to the stdout of atos, and uses a regular pipe as its stdin.

[ELF] - Change the way how we compute offsets for binary output.
Binary output feature is a bit confuzing. bfd and gold output differs a lot sometimes,
though it is important for FreeBSD mbr loaders.
Patch change the way how we compute file offsets for binary output.
This fixes PR31196.
Previously offsets were calculated basing on offsets and addresses of sections
from the same loads:
if (Sec == First)
return alignTo(Off, Target->MaxPageSize, Sec->Addr);
return First->Offset + Sec->Addr - First->Addr;
bfd assigns offsets for each section to VA - MinVA:
https://github.com/redox-os/binutils-gdb/blob/master/bfd/binary.c#L27
https://github.com/redox-os/binutils-gdb/blob/master/bfd/binary.c#L255
(LMA == VA usually)
This patch for now just stops creating phdrs for binary output.
An effect from this that no any additional calculation for offset is performed:
uintX_t getFileAlignment(uintX_t Off, OutputSectionBase *Sec) {
OutputSectionBase *First = Sec->FirstInPtLoad;
// If the section is not in a PT_LOAD, we have no other constraint.
if (!First)
return Off; //**First is always null, condition always happens**

that is similar to what bfd produce for mbr loader.

[sanitizer] Track architecture and UUID of modules in LoadedModule
When we enumerate loaded modules, we only track the module name and base address, which then has several problems on macOS. Dylibs and executables often have several architecture slices and not storing which architecture/UUID is actually loaded creates problems with symbolication: A file path + offset isn't enough to correctly symbolicate, since the offset can be valid in multiple slices. This is especially common for Haswell+ X86_64 machines, where x86_64h slices are preferred, but if one is not available, a regular x86_64 is loaded instead. But the same issue exists for i386 vs. x86_64 as well.
This patch adds tracking of arch and UUID for each LoadedModule. At this point, this information isn't used in reports, but this is the first step. The goal is to correctly identify which slice is loaded in symbolication, and also to output this information in reports so that we can tell which exact slices were loaded in post-mortem analysis.

Remove a wrong performance optimization.
This is a hack for single thread execution. We are using Color[0] and
Color[1] alternately on each iteration. This optimization is to look
at the next slot as opposted to the current slot to get recent results
early. Turns out that the assumption is wrong, because the other slots
are not always have the most recent values, but instead it may have
stale values of the previous iteration. This patch removes that
