[AVX512] Remove patterns for (v8f32 (X86vzmovl (insert_subvector undef, (v4f32 (scalar_to_vector FR32X:)), (iPTR 0)))) and the same for v4f64.

We don't have this same pattern for AVX2 so I don't believe we should have it for AVX512. We also didn't have it for v16f32.

Correct implementation:  Apparently I managed in r311683 to submit the wrong
version of the patch for this, so I'm correcting it now.

Summary:
Currently clang segfaults when invoked with `clang --autocomplete=`.
This patch adds the necessary boundary checks and some tests for corner cases like this.

In current OpenCL implementation some options are set in OpenCL RT/Driver, which causes discrepancy between online and offline paths.
Implement infrastructure to move options from OpenCL RT/Driver to AMDGPUToolChain using overloaded TranslateArgs() method.
Create map for default options values, as Options.td doesn't support default values (in contrast with OPTIONS.def).
Add two driver options: -On and -mNN (like -O3, -m64).
Some minor formatting changes to follow the clang-format style.

In RWPI code, globals that are not read-only are accessed relative to
the SB register (R9). This is achieved by explicitly generating an ADD
instruction between SB and an offset that we either load from a constant
pool or movw + movt into a register.

[InstCombine] Add test cases for folding (select (icmp ne/eq (and X, C1), (bitwiseop Y, C2), Y -> (bitwiseop Y, (shl/shr (and X, C1), C3)) or similar.

This is possible if C1 and C2 are both powers of 2. Or if binop is 'and' then ~C2 needs to be a power of 2.

We already support this for 'or', but we should be able to support 'and' and 'xor'. This will be enhanced by D37274.

[InstCombine] In foldSelectIntoOp, avoid creating a Constant before we know for sure we're going to use it and avoid an unnecessary call to m_APInt.

Instead of creating a Constant and then calling m_APInt with it (which will always return true). Just create an APInt initially, and use that for the checks in isSelect01 function. If it turns out we do need the Constant, create it from the APInt.

This is a refactor for a future patch that will do some more checks of the constant values here.

builds seem to be having trouble with it.

http://lab.llvm.org:8011/builders/clang-x86_64-linux-selfhost-modules-2/builds/11401

When trying to link lli-child-target, the linker reports missing symbols for
the 'Name' members of 'rpc::Function<OrcRPCNegotiate, FunctionIdT(std::string)>'
(base class for OrcRPCNegotiate) and 'rpc::Function<OrcRPCResponse, void()>'
(base class for OrcRPCResponse), despite there being definitions for these
immediately below the rpc::Function class template.

This looks like the same bug that bit OrcRemoteTargetClient/Server in r286920.

If multiple conditional branches are executed based on the same comparison, we can execute multiple conditional branches based on the result of one comparison on PPC. For example,

if (a == 0) { ... }
else if (a < 0) { ... }

can be executed by one compare and two conditional branches instead of two pairs of a compare and a conditional branch.

This patch identifies a code sequence of the two pairs of a compare and a conditional branch and merge the compares if possible.
To maximize the opportunity, we do canonicalization of code sequence before merging compares.
For the above example, the input for this pass looks like:

cmplwi r3, 0
beq    0, .LBB0_3
cmpwi  r3, -1
bgt    0, .LBB0_4

So, before merging two compares, we canonicalize it as

cmpwi  r3, 0       ; cmplwi and cmpwi yield same result for beq
beq    0, .LBB0_3
cmpwi  r3, 0       ; greather than -1 means greater or equal to 0
bge    0, .LBB0_4

The generated code should be

cmpwi  r3, 0
beq    0, .LBB0_3
bge    0, .LBB0_4

By exposing the constant initializer, the optimizer can fold many
of these constructs.

This is a recommit of r311857 that was reverted in r311898 because
an assert was hit when building Chromium.
We have to take into account that the GlobalVariable may be first
created with a different type than the initializer. This can
happen for example when the variable is a struct with tail padding
while the initializer does not have padding. In such case, the
variable needs to be destroyed an replaced with a new one with the
type of the initializer.

This patch introduces RemoteObjectClientLayer and RemoteObjectServerLayer,
which can be used to forward ORC object-layer operations from a JIT stack in
the client to a JIT stack (consisting only of object-layers) in the server.

This is a new way to support remote-JITing in LLVM. The previous approach
(supported by OrcRemoteTargetClient and OrcRemoteTargetServer) used a
remote-mapping memory manager that sat "beneath" the JIT stack and sent
fully-relocated binary blobs to the server. The main advantage of the new
approach is that relocatable objects can be cached on the server and re-used
(if the code that they represent hasn't changed), whereas fully-relocated blobs
can not (since the addresses they have been permanently bound to will change
from run to run).
