Petr Hosek 5f2e10e9c3 [Clang][NewPM] Don't bail out if the target machine is empty
This matches the behavior of the old pass manager. There are some
targets that don't have target machine at all (e.g. le32, spir) which
whose tests would never run with new pass manager. Similarly, we would
need to disable tests for targets that are disabled.

Rafael Espindola 699f5d6bbc Recommit r324107 again.
The difference from the previous try is that we no longer directly
access function declarations from position independent executables. It
should work, but currently doesn't with some linkers.

It now includes a fix to not mark available_externally definitions as
dso_local.

Original message:

Start setting dso_local in clang.

This starts adding dso_local to clang.

The hope is to eventually have TargetMachine::shouldAssumeDsoLocal go
away. My objective for now is to move enough of it to clang to remove
the need for the TargetMachine one to handle PIE copy relocations and
-fno-plt. With that it should then be easy to implement a
-fno-copy-reloc in clang.

This patch just adds the cases where we assume a symbol to be local
based on the file being compiled for an executable or a shared
library.

Rafael Espindola 880c3b24c5 Revert "Recommit r324107."
This reverts commit r324500.

The bots found two failures:

    ThreadSanitizer-x86_64 :: Linux/pie_no_aslr.cc
    ThreadSanitizer-x86_64 :: pie_test.cc

when using gold. The issue is a limitation in gold when building pie
binaries. I will investigate how to work around it.

Saleem Abdulrasool 5602709b98 Revert "Basic: match GCC behaviour for SuS macro"
This reverts commit SVN r294148.  Seems that it was mistaken, and GCC
does still define `__unix` and `unix` when in GNU mode.

Saleem Abdulrasool c5cddc9fa8 Basic: match GCC behaviour for SuS macro
GCC does not generate `__unix` nor `unix` macros.  The latter already
intrudes into the user's namespace and should be avoided.  Use the
canonical spelling of `__unix__` across all the targets.

JF Bastien 87ebb6859c Make test/Driver hermetic
Summary:
The includes shouldn't be there, use the compiler's built-in types/macros instead.

Rafael Espindola 925213b0fa Add 'not' to commands that are expected to fail.
This is at least good documentation, but also opens the possibility of
using pipefail.

Rafael Espindola fc3fc0c936 The clang driver has a fairly fancy support for executing gcc instead of
clang itself. This dates back to clang's early days and while it looks like
some of it is still used (for kext for example), other parts are probably dead.

Remove the -ccc-clang-archs option and associated code. I don't think there
is any remaining setup where clang doesn't support an architecture but it can
expect an working gcc cross compiler to be available.

A nice side effect is that tests no longer need to differentiate architectures
that are included in production builds of clang and those that are not.

Chandler Carruth f38e760777 Don't verify the name of the driver executable. It's not really relevent
to this test, and doesn't always start with 'clang' when fully resolved
on some build systems.

Ivan Krasin 69a990badb Clang/PNaCl: Improve test coverage for PNaClTargetInfo (type aligns), fixes nits:
- wrong alignment for double (it was 4, but 8 is desired),
- added checks for _REENTRANT define,
- fixed the issue that defines were not tested (because the check for inside #ifdef).
