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.

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.

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.

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).

Sometimes we create the ASTContext and thus the TranslationUnitDecl before we know the LangOptions. This should fix the asan buildbot failures after r312467.

The goal of this patch is twofold:
First, it removes a wrong comment (at least, not correctly describing
what the function does).
Then, it rewrites the function to use a StringSwitch where the
registers are enumerated explicitly instead of being computed
programmatically. Other than being much shorter, it's much easier to
read (and given the ABI won't change anytime soon, I don't think
there's need to generalize).
While here, I added an assert that the register name is always empty,
as the previous implementation of the function assumed so.

code duplication in the client, and improve error propagation.
This patch moves the OrcRemoteTarget rpc::Function declarations from
OrcRemoteTargetRPCAPI into their own namespaces under llvm::orc::remote so that
they can be used in new contexts (in particular, a remote-object-file adapter
layer that I will commit shortly).
Code duplication in OrcRemoteTargetClient (especially in loops processing the
code, rw-data and ro-data allocations) is removed by moving the loop bodies
into their own functions.
Error propagation is (slightly) improved by adding an ErrorReporter functor to
the OrcRemoteTargetClient -- Errors that can't be returned (because they occur
in destructors, or behind stable APIs that don't provide error returns) can be
sent to the ErrorReporter instead. Some methods in the Client API are also
changed to make better use of the Expected class: returning Expected<T>s rather
than returning Errors and taking T&s to store the results.

Summary:
The language server protocol specified 2 headers (Content-Length and Content-Type), but does not specify their sequence. It specifies that an empty line ends
headers. Clangd has been updated to handle arbitrary sequences of headers, extracting only the content length.
