Rafael Espindola adb73e6fb9 Try to fix the mingw build.
* MingW needs mapWindowsError.
* MingW is missing some entries in std::errc, but we don't use them.

Zachary Turner 39c422da57 Do not register and de-register PassRegistrationListeners during
construction and destruction.

PassRegistrationListener is intended for use as a generic listener.
In some cases, PassRegistrationListener-derived classes were being
created, and automatically registered and de-registered in static
constructors and destructors.  Since ManagedStatics are destroyed
prior to program shutdown, this leads to errors where an attempt is
made to access a ManagedStatic that has already been destroyed.

Zachary Turner a997d928fc Don't acquire the mutex during the destructor of PassRegistry.
This destructor is run as part of static program termination, and
so all ManagedStatics (including this lock) will have been
destroyed by llvm_shutdown.  Furthermore, if there is actually
a race condition during static program termination, then we are
just hiding a bug somewhere else, because other threads should
not be running at this point.

Jim Grosbach 7a930bf9ef ARM: honor hex immediate formatting for ldr/str i12 offsets.
Previously we would always print the offset as decimal, regardless of
the formatting requested. Now we use the formatImm() helper so the value
is printed as the client (LLDB in the motivating example) requested.

Before:
ldr.w r8, [sp, ] @ always

After:
ldr.w r8, [sp, #0xb4] @ when printing hex immediates
ldr.w r8, [sp, ] @ when printing decimal immediates

Rafael Espindola 5c4f829424 Use std::error_code instead of llvm::error_code.
The idea of this patch is to turn llvm/Support/system_error.h into a
transitional header that just brings in the erorr_code api to the llvm
namespace. I will remove it shortly afterwards.

The cases where the general idea needed some tweaking:

* std::errc is a namespace in msvc, so we cannot use "using std::errc". I could
add an #ifdef, but there were not that many uses, so I just added std:: to
them in this patch.

* Template specialization had to be moved to the std namespace in this
patch set already.

* The msvc implementation of default_error_condition doesn't seem to
provide the same transformations as we need. Not too surprising since
the standard doesn't actually say what "equivalent" means. I fixed the
problem by keeping our old mapping and using it at error_code
construction time.

Despite these shortcomings I think this is still a good thing. Some reasons:

* The different implementations of system_error might improve over time.
* It removes 925 lines of code from llvm already.
* It removes 6313 bytes from the text segment of the clang binary when
it is built with gcc and 2816 bytes when building with clang and
libstdc++.

Andrea Di Biagio c7af75f9a7 [X86] Refactor the logic to select horizontal adds/subs to a helper function.
This patch moves part of the logic implemented by the target specific
combine rules added at r210477 to a separate helper function.
This should make easier to add more rules for matching AVX/AVX2 horizontal
adds/subs.

This patch also fixes a problem caused by a wrong check performed on indices
of extract_vector_elt dag nodes in input to the scalar adds/subs.

New tests have been added to verify that we correctly check indices of
extract_vector_elt dag nodes when selecting a horizontal operation.

Saleem Abdulrasool faa29bd529 MC: add enumeration of WinEH data encoding
Most Windows platforms use auxiliary data for unwinding.  This information is
stored in the .pdata section.  The encoding format for the data differs between
architectures and Windows variants.  Windows MIPS and Alpha use identical
formats; Alpha64 is the same with different widths.  Windows x86_64 and Itanium
share the representation.  All Windows CE entries are identical irrespective of
the architecture.  ARMv7 (Windows [NT] on ARM) has its own format.

This enumeration will become the differentiator once the windows EH emission
infrastructure is generalised, allowing us to emit the necessary unwinding
information for Windows on ARM.
