This patch series adds support for the IBM z14 processor. This part includes:
- Basic support for the new processor and its features.
- Support for new instructions (except vector 32-bit float and 128-bit float).
- CodeGen for new instructions, including new LLVM intrinsics.
- Scheduler description for the new processor.
- Detection of z14 as host processor.
Support for the new 32-bit vector float and 128-bit vector float
instructions is provided by separate patches.

- Extracted the reading of the tokens out into a separate function.
- Replace 'Argument' with 'Parameter' when referring to the identifiers of the macro definition (as opposed to the supplied arguments - MacroArgs - during the macro invocation).
This is in preparation for submitting patches for review to implement __VA_OPT__ which will otherwise just keep lengthening the HandleDefineDirective function and making it less comprehensible.
I will also directly update some extra clang tooling that is broken by the change from Argument to Parameter.
Hopefully the bots will stay appeased.
Thanks!

In preparation for range extension thunks introduce a function that will
check whether a branch identified by a relocation type at a source address
can reach a destination.
For targets where range extension thunks are not supported the function will
return true as it is not expected that branches are out of range. An
implementation has been provided for ARM.

- We should call `preloadInvariantLoads` to make sure that code is
generated for invariant loads in the kernel.

The target-independent lowering works fine, except concatenating 32-bit
words. Add a pattern to generate A2_combinew instead of 64-bit asl/or.

Prevent store merge from merging stores into an invalid 128-bit store
(realized as a f128 value in the context of the noimplicitfloat
attribute). Previously, such stores are immediately split back into
valid stores.

Summary:
Previously, CodeGen checked first src operand type to determine if omod is supported by instruction. This isn't correct for some instructions: e.g. V_CMP_EQ_F32 has floating-point src operands but desn't support omod.
Changed .td files to check if dst operand instead of src operand.

Summary:
The current yaml::Input constructor takes a StringRef of data as its
first parameter, discarding any filename information that may have been
present when a YAML file was opened. Add an alterate yaml::Input
constructor that takes a MemoryBufferRef, which can have a filename
associated with it. This leads to clearer diagnostic messages.

This is PR33766.
-F name
--filter=name
When creating an ELF shared object, set the internal DT_FILTER field to the specified name. This tells the dynamic linker that the symbol table of the shared object which is being created should be used as a filter on the symbol table of the shared object name.
If you later link a program against this filter object, then, when you run the program, the dynamic linker will see the DT_FILTER field. The dynamic linker will resolve symbols according to the symbol table of the filter object as usual, but it will actually link to the definitions found in the shared object name. Thus the filter object can be used to select a subset of the symbols provided by the object name.

Changes are: got all atomics to accept volatile pointers that allowed
to simplify many type conversions. Windows specific code fixed correspondingly.

We're already using it in 64-bit builds because 64-bit MSVC doesn't support inline assembly.
As far as I know we were using inline assembly because at the time the code was added we had to support MSVC 2008 pre-SP1 while the intrinsic was added to MSVC in SP1. Now that we don't have to support that we should be able to just use the intrinsic.
