This extends the blocks support to support blocks with a dynamically linked
blocks runtime. The previous code generation would work only for static builds
of the blocks runtime. Mark the block "isa" pointers and functions as dllimport
if no explicit declaration marked with __declspec(dllexport) is found. This
additional check allows for the use of the functionality in the runtime library
if desired.

OpenCL has large number of "builtin" functions ("builtin" in the sense of OpenCL spec) which are defined in header files. To compile OpenCL kernels using these builtin functions, a header file is needed.
This header file is based on the Khronos implementation (https://github.com/KhronosGroup/SPIR/blob/spirv-1.0/lib/Headers/opencl.h) with heavy refactoring.

This patch removes the llvm intrinsics VPMOVSX and (V)PMOVZX sign/zero extension intrinsics and auto-upgrades to SEXT/ZEXT calls instead. We already did this for SSE41 PMOVSX sometime ago so much of that implementation can be reused.
Reapplied now that the the companion patch (D20684) removes/auto-upgrade the clang intrinsics has been committed.

Summary:
When RF_NullMapMissingGlobalValues is set, mapValue can return null
for GlobalValue. When mapping the operands of a constant that is
referenced from metadata, we need to handle this case and actually
return null instead of mapping this constant.

Add determination of statements that contain, in particular,
matrix multiplications and can be optimized with [1] to try to
get close-to-peak performance. It can be enabled
via polly-pm-based-opts, which is false by default.

We were producing R_X86_64_GOTPCRELX for invalid instructions and
sometimes producing R_X86_64_GOTPCRELX instead of
R_X86_64_REX_GOTPCRELX.

It would be better to check the valid/expected size of the immediate operand, but this is
generally better than what we print right now.

Quite a few libcxx tests seem to follow the format:
#if _LIBCPP_STD_VER > X
// Do test.
#else
// Empty test.
#endif
We should instead use the UNSUPPORTED lit directive to exclude the test on
earlier C++ standards. This gives us a more accurate number of test passes
for those standards and avoids unnecessary conflicts with other lit
directives on the same tests.

The VPMOVSX and (V)PMOVZX sign/zero extension intrinsics can be safely represented as generic __builtin_convertvector calls instead of x86 intrinsics.
This patch removes the clang builtins and their use in the sse2/avx headers - a companion patch will remove/auto-upgrade the llvm intrinsics.
Note: We already did this for SSE41 PMOVSX sometime ago.

This converts remaining uses of ByteStream, which was still
left in the symbol stream and type stream, to using the new
StreamInterface zero-copy classes.
RecordIterator is finally deleted, so this is the only way left
now. Additionally, more error checking is added when iterating
the various streams.
With this, the transition to zero copy pdb access is complete.

In case of MIPS, GP-relative relocations always resolve to a definition
in a regular input file, ignoring the one-definition rule. Such
relocations are used to setup GP relative offsets in a function's
prologue. So we, for example, should not attempt to create a dynamic
relocation even if the target symbol is preemptible.
Fixes bug 27880.

Composing subreg_loreg with subreg_oveflow leads to strange results with
lane masks for register classes with subreg_loreg. In particular, dead
lane detection generates incorrect code.
