Simon Atanasyan bb399f3d57 [ELF][Mips] Do not merge ELF flags in the `isCompatible` routine 
We do not need to merge ELF flags from DSO. But `isCompatible` is called
for all input files. So this change move ELF flags merging into the
MipsELFFile class.

Adhemerval Zanella f3c1c065aa [ELF/AArch64] Fix local TLS relocations 
This patch fixes the R_AARCH64_TLSLE_ADD_TPREL_HI12 and R_AARCH64_TLSLE_ADD_TPREL_LO12_NC
handling by using the correct offset by using the target layout along with
aarch64 alignments requirements.

It fixes the TLS test-suite SingleSource failures for aarch64:

* SingleSource/UnitTests/Threads/2010-12-08-tls.execution_time
* SingleSource/UnitTests/Threads/tls.execution_time

Simon Atanasyan 0b22359858 [ELF] Fix lld when no unique sections is used 
Original patch of Shankar Easwaran with additional test case.
The yaml2obj does not allow to create an object file with non-unique
sections names so the fix uses a binary input object file in the test
case.

Denis Protivensky 575f7d4f1c [ARM] Ability to add GOT and PLTGOT entries for same symbol 
These two serve different purpose:
PLTGOT entries are (usually) lazily resolved and serve as trampolines
to correctly call dynamically linked functions. They often have
R_*_JUMP_SLOT dynamic relocation type used.
Simple GOT entries hold other things, one of them may be
R_*_GLOB_DAT to correctly reference global and static data. This
is also used to hold dynamically linked function's address.

To properly handle cases when shared object's function is called
and at the same time its address is taken, we need to be able to have
both GOT and PLTGOT entries bearing different dynamic relocation types
for the same symbol.

Denis Protivensky 214122cffc [ARM] Implement R_ARM_GLOB_DAT for GOT entries 
This is used when referencing global or static data in shared

function call is made indirectly.

Leny Kholodov bde4144338 [ARM] Generation of .ARM.exidx/.ARM.extab sections 
This patch provides generation of .ARM.exidx & .ARM.extab sections which are
used for unwinding. The patch adds new content type typeARMExidx for atoms from
.ARM.exidx section and integration of atoms with such type to the ELF
ReaderWriter. exidx.test has been added with checking of contents of .ARM.exidx
section and .ARM.extab section.
