The original failure contained an arithmetic conversion think-o (on line 419 of
EHFrameSupport.cpp) that could cause failures on 32-bit platforms. The issue
should be fixed in this patch.

[JITLink] Optimize GOTPCRELX Relocations
This patch optimize the GOTPCRELX Reloations, which is described in X86-64 psabi chapter B.2. And Not all optimization of this chapter is implemented.
1. Convert call and jmp has been implemented
2. Convert mov, but the optimization that when the symbol is defined in the lower 32-bit address space, memory operand in `mov` can be convertted into immediate operand has not been implemented.
3. Conver Test and Binop has not been implemented.
The new test file named ELF_got_plt_optimizations.s has been added, and I moved some test cases about optimization of got/plt from ELF_x86_64_small_pic_relocations.s to the new test file.
By referencing the lld, so, the optimization `Convert call and jmp` is not same as what psabi says, and I have explained it in the comment.

[JITLink] Update ELF_x86_64 's edge kind to generic edge kind
This patch uses a switch statement to map the ELF_x86_64's edge kind to generic edge kind, and merge the ELF_x86_64 's applyFixup function to the x86_64 's applyFixup function. Some edge kinds were not have corresponding generic edge kinds, so I added three generic edge kinds asa follows:
1. RequestGOTAndTransformToDelta64, which is similar to RequestGOTAndTransformToDelta32.
2. GOTDelta64. This generic kind is similar to Delta64, except the GOTDelta64 computes the delta relative to GOTSymbol
3. RequestGOTAndTransformToGOTDelta64. This edge kind was used to deal with ELF_x86_64's GOT64 edge kind, it request the fixGOTEdge function to change the target to GOT entry, and set the edge kind to generic edge kind GOTDelta64.
These added generic edge kinds may named haphazardly, or can't express its meaning well.

[JITLink] Switch from StringRef to ArrayRef<char>, add some generic x86-64 utils
Adds utilities for creating anonymous pointers and jump stubs to x86_64.h. These
are used by the GOT and Stubs builder, but may also be used by pass writers who
want to create pointer stubs for indirection.
This patch also switches the underlying type for LinkGraph content from
StringRef to ArrayRef<char>. This avoids any confusion when working with buffers
that contain null bytes in the middle like, for example, a newly added null
pointer content array. ;)

[JITLink][MachO][x86-64] Introduce generic x86-64 support.
This patch introduces generic x86-64 edge kinds, and refactors the MachO/x86-64
backend to use these edge kinds. This simplifies the implementation of the
MachO/x86-64 backend and makes it possible to write generic x86-64 passes and
utilities.
The new edge kinds are different from the original set used in the MachO/x86-64
backend. Several edge kinds that were not meaningfully distinguished in that
backend (e.g. the PCRelMinusN edges) have been merged into single edge kinds in
the new scheme (these edge kinds can be reintroduced later if we find a use for
them). At the same time, new edge kinds have been introduced to convey extra
information about the state of the graph. E.g. The Request*AndTransformTo**
edges represent GOT/TLVP relocations prior to synthesis of the GOT/TLVP
entries, and the 'Relaxable' suffix distinguishes edges that are candidates for
optimization from edges which should be left as-is (e.g. to enable runtime
redirection).
ELF/x86-64 will be refactored to use these generic edges at some point in the
future, and I anticipate a similar refactor to create a generic arm64 support
header too.
