Command line options --arm-target1-rel and --arm-target1-abs have been renamed to be compatible with GNU linkers.
Two tests have been updated:
test/elf/options/target-specific-args.test
test/elf/ARM/rel-arm-target1.test

According to the code model (ARM, Thumb, Thumb2) this patch updates the b/bl/blx 0 instructions with NOP.
test/elf/ARM/weak-branch.test has been added with tests for all available NOP (A1, T1, T2 encodings).

The TargetLayout class puts two sections into the same segment if they
have equal segment types and the same section flags (SHF_xxx). To be
able to merge some sort of sections into the same segment we drop some
flags before comparison. For example to merge string sections into Data
segment we drop SHF_STRINGS and SHF_MERGE flags.
The patch allows TargetLayout descendants to drop some target specific
section flags. MIPS target needs that to merge .MIPS.options section
which has SHF_MIPS_NOSTRIP flag into the LOAD segment.

The `OutputSection::appendSection()` method always gets a pointer
to the `Section` class descendants. So it is not necessary to keep them
in the vector of `Chunk` pointers.
No functional changes.

There's (almost) never need to keep .L symbols around for production
builds. In fact, the FreeBSD kernel explicitly specify -X beacuse the
size impact (and the subsequent performance impact) might be significant,
because we keep symbols in memory.
I was tempted to make this the default, but I haven't (yet).

Before we only accepted --dynamic-linker=<file> and -dynamic-linker <file>
but older versions of GNU ld (e.g. 2.17.50) accept this other form, so
try to be compatible.

HexagonEncodings.h contains a list of bitmasks. The file is used
only by HexagonRelocationHandler.cpp. The header is odd in the sense
that it uses struct Instruction but it doesn't define the data type.
This patch moves the struct definition to the header.

This function is too long and complicated. Looks like new code was
added incrementaly without any refactoring. Maybe no one can describe
its exact semantics any more? It even contains copy-pastes inside it.
This patch is an (incomplete) attempt to simplify the function.
I tried to mechanically translate code to another form more intelligible.
I don't still understand the whole picture, but this patch shouldn't
change the linker's functionality.

That helps to correctly write content of hash table if target and host
endianness are not the same. Right now that commit does not affect
any supported targets.
