Remove include of 'type_info' from ext-int test.

Originally I thought that I needed to do a #include to trick the
compiler into letting me use typeid I believe, but Aaron explained that
it was just looking for the type_info type.  I had to give it some
public/private members to make it emit the same as before, but this
ought to be a 'perfect' replacement.

[InstCombine] Fold `(a & ~b) & ~c` to `a & ~(b | c)`

  %not1 = xor i32 %b, -1
  %not2 = xor i32 %c, -1
  %and1 = and i32 %a, %not1
  %and2 = and i32 %and1, %not2
=>
  %i1 = or i32 %b, %c
  %i2 = xor i32 %1, -1
  %and2 = and i32 %i2, %a

[libc++] Fix incorrect main() signatures in the tests

Those creep up from time to time. We need to use `int main(int, char**)`
because in freestanding mode, `main` doesn't get special treatment and
special mangling, so we setup a symbol alias from the mangled version of
`main(int, char**)` to `extern "C" main`. That only works if all the tests
are consistent about how they define their main function.

Commit 40163f1df8c60f987e8adc0cb78edb289f73b771 by spatel
[x86] add special-case lowering for usubsat for AVX512

This is a small extension of D112095 to avoid another regression
seen with D112085.
In this case, we allow the same conversion from usubsat to ALU
ops if the target supports vpternlog.

That pattern will get converted later in X86DAGToDAGISel::tryVPTERNLOG().
This seems better than putting a magic immediate constant directly in
this code to create the exact vpternlog that we need. It's possible that
there are other special-cases along these lines, so we should try to
keep all of the vpternlog magic in one place.

[Tests] Add tests for non-speculatable ephemeral values

The loads in these examples are currently not considered ephemeral
because they are not speculatable.

[libc++abi] Guard include of <unistd.h> behind __has_include

This doesn't change anything on platforms that have <unistd.h>, but
it will allow this file to compile on platforms that do not.

[libunwind] Revert "Use the from-scratch testing configuration by default"

This reverts commit 5a8ad80b6fa5cbad58b78384f534b78fca863e7f, which broke
the Bootstrapping build. I'm reverting until we've fixed the issue.
