Nico Weber 3a89be1b25 Add REQUIRES: arm-registered-target to test using an arm-apple-ios triple.
Else, the test fails in LLVM_TARGETS_TO_BUILD=X86 builds like so:
bin/llvm-mc: : error: unable to get target for 'arm64-apple-ios7.0.0'

Nico Weber 05c988473f LTOModule::isBitcodeFile() shouldn't assert when returning false.
Fixes a bunch of assert-on-invalid-bitcode regressions after 315483.
Expected<> calls assertIsChecked() in its dtor, and operator bool() only calls
setChecked() if there's no error. So for functions that don't return an error
itself, the Expected<> version needs explicit code to disarm the error that the
ErrorOr<> code didn't need.

Francis Ricci a7bf226529 [test] Enable LeakSanitizer on 64-bit Darwin ASan llvm builds
Summary:
Also disables leak checking on lto tests, due to many leaks reported
in the system's ld64.

Bruno Cardoso Lopes 358e60a6b3 [LIT][Darwin] Change %ld64 to be prefixed with DYLD_INSERT_LIBRARIES
Followup from r277778, after Mehdi's comments.

Expand %ld64 to perform the necessary preload instead, that way new
tests do not need to worry about setting up DYLD_INSERT_LIBRARIES
themselves.

Bruno Cardoso Lopes 8daab7582b [LIT][Darwin] Preload libclang_rt.asan_osx_dynamic.dylib when necessary
Green Dragon's darwin stage2 asan bot fails on some checks:
http://lab.llvm.org:8080/green/job/clang-stage2-cmake-RgSan_check

  test/tools/lto/hide-linkonce-odr.ll
  test/tools/lto/opt-level.ll

ERROR: Interceptors are not working. This may be because
AddressSanitizer is loaded too late (e.g. via dlopen)

To fix this, %ld64 needs to load 'libclang_rt.asan_osx_dynamic.dylib'
before libLTO.dylib, via DYLD_INSERT_LIBRARIES. This won't work by
updating config.environment, since some shim binary in the way scrubs
the env vars. Instead, provide the path to this lib through %asanrtlib,
which can then be used by tests directly with DYLD_INSERT_LIBRARIES.

Mehdi Amini 022b5bcb7a LTOCodeGenerator: add linkonce(_odr) to "llvm.compiler.used" when present in "MustPreserve" set
If the linker requested to preserve a linkonce function, we should
honor this even if we drop all uses.
We explicitely avoid turning them into weak_odr (unlike the first
version of this patch in r267644), because the codegen can be
different on Darwin: because of `llvm::canBeOmittedFromSymbolTable()`
we may emit the symbol as weak_def_can_be_hidden instead of
weak_definition.

Mehdi Amini 752ffe9c5f Revert "LTOCodeGenerator: turns linkonce(_odr) into weak_(odr) when present "MustPreserve" set"
This reverts commit r267644. Turning linkonce_odr into weak_odr is
a sementic change on Darwin: because of
`llvm::canBeOmittedFromSymbolTable()` we may emit the symbol as
weak_def_can_be_hidden instead of weak_definition.

Adam Nemet 106fedab6f [LTO] Support Statistics
Summary:
I thought -Xlinker -mllvm -Xlinker -stats worked at some point but maybe
it never did.

For clang, I believe that stats are printed from cc1_main.  This patch
also prints them for LTO, specifically right after codegen happens.

I only looked at the C API for LTO briefly to see if this is a good
place.  Probably there are still cases where this wouldn't be printed
but it seems to be working for the common case.  I also experimented
putting this in the LTOCodeGenerator destructor but that didn't trigger
for me because ld64 does not destroy the LTOCodeGenerator.

Justin Bogner 45291391b2 lto: Avoid relying on the environment for this test

on setting DYLD_LIBRARY_PATH.

Peter Collingbourne bbdc26ba1b test: Make a start on a test suite for libLTO.
This works in a similar way to the gold plugin tests. We search for a compatible
linker on $PATH and use it to run tests against our just-built libLTO. To start
with, test the just added opt level functionality.
