Rafael Espindola 3e7d6fc2c6 Define TrapInst for ppc64.
This is nice for testing since it is the first TrapInst whose bytes
are not all the same.

Sean Fertile 227d4399bf [PPC64] Minor changes for Plt relocations.
The Plt relative relocations are R_PPC64_JMP_SLOT in the V2 abi, and we only
reserve 2 double words instead of 3 at the start of the array of PLT entries for
lazy linking.

Rui Ueyama f001ead490 Do not use template for check{Int,UInt,IntUInt,Alignment}.
Template is just unnecessary.

Zaara Syeda 5dd6bd9631 [ELF][PPC64] Fix getRelExpr for R_PPC64_REL16_LO and R_PPC64_REL16_HA
The relocations R_PPC64_REL16_LO and R_PPC64_REL16_HA should return R_PC
for getRelExpr since they compute #lo(S + A – P) and #ha(S + A – P).

Zaara Syeda 52ed6eb8d9 [ELF] Add basic support for PPC LE
This patch adds changes to start supporting the Power 64-Bit ELF V2 ABI.
This includes:
- Changing the ElfSym::GlobalOffsetTable to be named .TOC.
- Creating a GotHeader so the first entry in the .got is .TOC.
- Setting the e_flags to be 1 for ELF V1 and 2 for ELF V2

Rui Ueyama f52496e1e0 Rename SymbolBody -> Symbol
Now that we have only SymbolBody as the symbol class. So, "SymbolBody"
is a bit strange name now. This is a mechanical change generated by

  perl -i -pe s/SymbolBody/Symbol/g $(git grep -l SymbolBody lld/ELF lld/COFF)

nd clang-format-diff.

Bob Haarman b8a59c8aa5 [lld] unified COFF and ELF error handling on new Common/ErrorHandler
Summary:
The COFF linker and the ELF linker have long had similar but separate
Error.h and Error.cpp files to implement error handling. This change
introduces new error handling code in Common/ErrorHandler.h, changes the
COFF and ELF linkers to use it, and removes the old, separate
implementations.

Rui Ueyama be85529d2b Remove one parameter from Target::getRelExpr.
A section was passed to getRelExpr just to create an error message.
But if there's an invalid relocation, we would eventually report it
in relocateOne. So we don't have to pass a section to getRelExpr.

Rui Ueyama 67533a2cb3 Define RelType to represent relocation types.
We were using uint32_t as the type of relocation kind. It has a
readability issue because what Type really means in `uint32_t Type`
is not obvious. It could be a section type, a symbol type or a
relocation type.

Since we do not do any arithemetic operations on relocation types
(e.g. adding one to R_X86_64_PC32 doesn't make sense), it would be
more natural if they are represented as enums. Unfortunately, that
is not doable because relocation type definitions are spread into
multiple header files.

So I decided to use typedef. This still should be better than the
plain uint32_t because the intended type is now obvious.

Rafael Espindola 3bab91332f Fix which file is in an error message.
When reporting an invalid relocation we were blaming the destination
file instead of the file with the relocation.

Rui Ueyama 21c0a9ceeb Split Target.cpp into small files.
Target.cpp contains code for all the targets that LLD supports. It was
simple and easy, but as the number of supported targets increased,
it got messy.

This patch splits the file into per-target files under ELF/arch directory.
