a5f1ae1ad0 ELF: Use short variable names in <Arch>RelocationHandlers.cpp.
Functions in the files are hard to read because of line wrapping.
Use shorter names for local variables so that the lines fit
within 80 columns.

7cea026a63 Add {read,write}{16,32,64}{le,be} functions.
Nothing wrong with reinterpret_cast<llvm::support::ulittle32_t *>(loc),
but that's redundant and not great from readability point of view.
The new functions are wrappers for that kind of reinterpet_casts.

Surprisingly or unsurprisingly, there was no use of big endian read
and write. {read,write}{16,32,64}be have no user. But I think they
still worth to be there in the header for completeness.

a8c4d48478 ELF: Support detection of relocation errors during processing
At the moment errors in relocation processing such as out of range
values are not detected or at best trapped by asserts which will not
be present in release builds. This patch adds support for checking
error return values from applyRelocation() calls and printing an
appropriate error message. It also adds support for printing multiple
errors rather than just the first one.

4c81bb7e3f ELF: Add a standard method for unknown relocation errors
At present each TargetRelocationHandler generates a pretty similar error
string and calls llvm_unreachable() when encountering an unknown
relocation. This is not ideal for two reasons:

1. llvm_unreachable disappears in release builds but we still want to
   know if we encountered a relocation we couldn't handle in release
   builds.

2. Duplication is bad - there is no need to have a per-architecture error
   message.

This change adds a test for AArch64 to test whether or not the error
message actually works. The other architectures have not been tested
but they compile and check-lld passes.

ac23808619 [ELF] Add Readers for all the ELF subtargets.
This would permit the ELF reader to check the architecture that is being
selected by the linking process.

This patch also sorts the include files according to LLVM conventions.
