8495e8b1e9 Fix known issues which blow up the process after dlopen("libthr.so")
(or loading a dso linked to libthr.so into process which was not
linked against threading library).

- Remove libthr interposers of the libc functions, including
  __error(). Instead, functions calls are indirected through the
  interposing table, similar to how pthread stubs in libc are already
  done.  Libc by default points either to syscall trampolines or to
  existing libc implementations.  On libthr load, libthr rewrites the
  pointers to the cancellable implementations already in libthr.  The
  interposition table is separate from pthreads stubs indirection
  table to not pull pthreads stubs into static binaries.

- Postpone the malloc(3) internal mutexes initialization until libthr
  is loaded.  This avoids recursion between calloc(3) and static
  pthread_mutex_t initialization.

- Reinstall signal handlers with wrapper on libthr load.  The
  _rtld_is_dlopened(3) is used to avoid useless calls to sigaction(2)
  when libthr is statically referenced from the main binary.

In the process, fix openat(2), swapcontext(2) and setcontext(2)
interposing.  The libc symbols were exported at different versions
than libthr interposers.  Export both libc and libthr versions from
libc now, with default set to the higher version from libthr.

Remove unused and disconnected swapcontext(3) userspace implementation
from libc/gen.

d79f904ad2 Link lib/libc/c063 tests to the build.
Some files lack required #include <sys/stat.h>. The #ifdef is per ngie's
request; the includes are clearly necessary for struct stat.

The faccessat test fails because it tries to use AT_SYMLINK_NOFOLLOW with
faccessat(), which is not specified by POSIX.1-2008.

PowerPC: CTR shouldn't fire if a TLS call is in the loop

  Determining the address of a TLS variable results in a function call in
  certain TLS models.  This means that a simple ICmpInst might actually
  result in invalidating the CTR register.

  In such cases, do not attempt to rely on the CTR register for loop
  optimization purposes.

630590abbc Pull in r221703 from upstream llvm trunk (by Bill Schmidt):
[PowerPC] Replace foul hackery with real calls to __tls_get_addr

  My original support for the general dynamic and local dynamic TLS
  models contained some fairly obtuse hacks to generate calls to
  __tls_get_addr when lowering a TargetGlobalAddress.  Rather than
  generating real calls, special GET_TLS_ADDR nodes were used to wrap
  the calls and only reveal them at assembly time.  I attempted to
  provide correct parameter and return values by chaining CopyToReg and
  CopyFromReg nodes onto the GET_TLS_ADDR nodes, but this was also not
  fully correct.  Problems were seen with two back-to-back stores to TLS
  variables, where the call sequences ended up overlapping with unhappy
  results.  Additionally, since these weren't real calls, the proper
  register side effects of a call were not recorded, so clobbered values
  were kept live across the calls.

  The proper thing to do is to lower these into calls in the first
  place.  This is relatively straightforward; see the changes to
  PPCTargetLowering::LowerGlobalTLSAddress() in PPCISelLowering.cpp.
  The changes here are standard call lowering, except that we need to
  track the fact that these calls will require a relocation.  This is
  done by adding a machine operand flag of MO_TLSLD or MO_TLSGD to the
  TargetGlobalAddress operand that appears earlier in the sequence.

  The calls to LowerCallTo() eventually find their way to
  LowerCall_64SVR4() or LowerCall_32SVR4(), which call FinishCall(),
  which calls PrepareCall().  In PrepareCall(), we detect the calls to
  __tls_get_addr and immediately snag the TargetGlobalTLSAddress with
  the annotated relocation information.  This becomes an extra operand
  on the call following the callee, which is expected for nodes of type
  tlscall.  We change the call opcode to CALL_TLS for this case.  Back
  in FinishCall(), we change it again to CALL_NOP_TLS for 64-bit only,
  since we require a TOC-restore nop following the call for the 64-bit
  ABIs.

  During selection, patterns in PPCInstrInfo.td and PPCInstr64Bit.td
  convert the CALL_TLS nodes into BL_TLS nodes, and convert the
  CALL_NOP_TLS nodes into BL8_NOP_TLS nodes.  This replaces the code
  removed from PPCAsmPrinter.cpp, as the BL_TLS or BL8_NOP_TLS
  nodes can now be emitted normally using their patterns and the
  associated printTLSCall print method.

  Finally, as a result of these changes, all references to get-tls-addr
  in its various guises are no longer used, so they have been removed.

  There are existing TLS tests to verify the changes haven't messed
  anything up).  I've added one new test that verifies that the problem
  with the original code has been fixed.

This fixes a fatal "Bad machine code" error when compiling parts of
libgomp for 32-bit PowerPC.
