On ELF target, the assembler normally generates code which can go into a
shared library where non-weak symbols can be preempted. The -mno-shared
option tells the assembler to generate code not for a shared library,
where non-weak symbols won't be preempted. The resulting code is slightly
smaller. This option mainly affects the handling of branch instructions.

Currently every fixup in the current segment is checked when relaxing
trampoline frag. This is very expensive. Make a searchable array of
fixups pointing at potentially oversized jumps at the beginning of every
relaxation pass and only check subset of this cache in the reach of
single jump from the trampoline frag currently being relaxed.

This x86 assembler patch:
https://sourceware.org/ml/binutils/2001-11/msg00344.html
generates a .note section for .arch directive so that GDB can tell which
architecture an i386 binary belongs:

However, x86 assembly code can have any instructions. A .note section

Extend the address modifier parsing to distinguish between the
modifers used in LDR literal and LDR register offset address modes.
The current parser incorrectly accepts the :got: modifier on a
register offset instruction resulting in silent corruption of the
output binary.
The current implementation of the :got: assembler modifier does not
distinguish the ADR and ADRP instruction. The :got: modifier does not
make sense on and ADR instruction and should be error'd rather than
the current behavior of applying an inappropriate relocation to the
output and scrambling the underlying instruction silently.
Adds support to the assembler to write out data for tracking the use of
.org and .align directives. This data is collected within the assembler
and written out to a section ".avr.prop" (if there's anything to write
out).
This patch does not add any tests. The next patch in this series will
add a better mechanism for visualising the contents of .avr.prop which
will make writing tests much easier.
This patch also does not make any use of this collected data, that will
also come along in a later patch; the intended consumer is the linker,
during linker relaxation this information will be used to ensure that
the .org and .align directives are honoured.

gcc-5 correctly complains "loop exit may only be reached after
undefined behavior". I was going to correct this by checking the
index before dereferencing the array rather than the other way around,
but then I noticed it is possible for extract_cmd to write the
terminating zero one past the end of "cmd". Fixing that means no
index check is needed in md_assemble.

When runtime patching code (like e.g. done by the Linux kernel) there
may be cases where the set of stack frame alterations differs between
unpatched and patched code. Consequently the corresponding unwind data
needs patching too. Locating the right places within an FDE, however,
is rather cumbersome without a way to insert labels in the resulting
section. Hence this patch introduces a new directive, .cfi_label. Note
that with the way CFI data gets emitted currently (at the end of the
assembly process) this can't support local FB- and dollar-labels.
