ca17841fc4 Run the last iteration of parallel_for_loop using a threadpool.
Remainders of tasks were ran in the main thread, so parallel_for_each
could theoretically take 2x time than the ideal.

ad3ba6be31 Revert "Recover better from an incompatible .pcm file being provided by -fmodule-file=. We try to include the headers of the module textually in this case, still enforcing the modules semantic rules. In order to make that work, we need to still track that we're entering and leaving the module. Also, if the module was also marked as unavailable (perhaps because it was missing a file), we shouldn't mark the module unavailable -- we don't need the module to be complete if we're going to enter it textually."
This reverts commit r288449.

I believe that this is currently faulty wrt. modules being imported
inside namespaces. Adding these lines to the new test:

  namespace n {
  #include "foo.h"
  }

Makes it break with

  fatal error: import of module 'M' appears within namespace 'n'

However, I believe it should fail with

  error: redundant #include of module 'M' appears within namespace 'n'

I have tracked this down to us now inserting a tok::annot_module_begin
instead of a tok::annot_module_include in
Preprocessor::HandleIncludeDirective() and then later in
Parser::parseMisplacedModuleImport(), we hit the code path for
tok::annot_module_begin, which doesn't set FromInclude of
checkModuleImportContext to true (thus leading to the "wrong"
diagnostic).

8f34233318 [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.

02460bac8b Choose better hash values for std::monostate and valueless variants.
Previously these hashes were 0 and -1 respectively. These seem like common
sentinel values and should be avoided to prevent needless collisions.

This patch changes those values to different arbitrary numbers, which should
hopefully cause less collisions. Because I couldn't help myself I choose the
fundamental constants for gravity and the speed of light.

1b3d34a298 [ELF] - Implemented R_386_16 and R_386PC16 relocations
A program or object file using R_386_8, R_386_16, R_386_PC16 or R_386_PC8
relocations is not conformant to latest ABI. The R_386_16, and R_386_8
relocations truncate the computed value to 16 - bits and 8 - bits
respectively. R_386_PC16 and R_386_16 are used by some
applications, for example by FreeBSD loaders.

Previously we did not take addend in account for these relocation,
counting it as 0, what is wrong and was a reason of hangs.

This patch needed for example for FreeBSD pmbr (protective mbr).
