Rui Ueyama a5b6859ac4 ELF: Use less templates for ELF types.
These classes are templated but actually instantiated for only
one ELF type.

Rui Ueyama ad87e54f1a ELF: Define ELF{32,64}{LE,BE} types and use them everywhere.

Rui Ueyama 7d5492d9ab ELF: Move registerRelocationNames() from TargetHandler to <Arch>ELFLinkingContext.
registerRelocationNames() function is called to register all known
ELF relocation types to the central registry. Since we have separate
LinkingContext class for each ELF machine type, we need to call the
function for each LinkingContext.

However, the function belonged to TargetHandler instead of LinkingContext.
So we needed to do ctx.getTargetHandler().registerRelocationNames().
This patch removes that redundant getTargetHandler call by moving the
function from TargetHandler to LinkingContext.

Conceptually this patch is small, but in reality it's not that small.
It's because the same code is copied to each architecture.
Most of this patch is just repetition. We need to merge them, but
that cannot be done in this patch.

Rui Ueyama 943206da8e ELF: x86, x86-64, ARM, AArch64: Remove architecture name prefixes from class members.

Rui Ueyama 4507003622 ELF: Remove <Arch>TargetHandler::kindString.
<Arch>TargetHandler::kindString is a static member variable
containg a list of names of relocation types.

The member is used only by one function, registerRelocationNames,
so they don't have to be a static member.

This patch makes the visibility of the data narrower by making
them file-scoped variables in small files.

Greg Fitzgerald 8a1887f1f1 [ELF] Minimal implementation for ARM static linking
The code is able to statically link the simplest case of:

  int main() { return 0; }

* Only works with ARM code - no Thumb code, no interwork (-marm -mno-thumb-interwork)
* musl libc built with no interwork and no Thumb code
