Fix incorrect handling of STT_COMMON symbols in shared libraries.
The gABI allows STT_COMMON symbols to appear in executables and shared
objects, so that the dynamic loader can resolve commons across modules.
When reading a shared object, however, an STT_COMMON symbol should be
treated as a regular definition at link time.
In a relocatable object, the gABI requires that any STT_COMMON symbols
must also be defined in the special SHN_COMMON section (which we extend
to include target-specific small and large common sections). Thus,
there is no need for gold to treat STT_COMMON symbols as common unless
the st_shndx field is also set to a common section.

Fix gold to group sections correctly via linker script.
In PR 15370, it is noted that gold does not distinguish between
"*(.foo .bar)" and "*(.foo) *(.bar)" in linker scripts. In both
cases, gold groups all .foo sections together, followed by all
.bar sections, whereas in the first case, it should collect all
.foo and .bar sections in the order seen.
If you add sort specs, the Gnu linker has some bizarre corner
cases that I do not try to replicate. In particular,
"*(SORT_BY_NAME(.foo) SORT_BY_NAME(.bar))" does the same thing
as "*(.foo) *(.bar)". But if you apply a sort spec
to just one of several patterns, say, "*(SORT_BY_NAME(.foo) .bar)",
the Gnu linker will collect any .bar section it sees before the
first .foo, then all .foo sections, then all remaining .bar
sections. With this patch, if any of the input patterns have a
sort spec, gold will group them all as it did before; e.g.,
all .foo sections followed by all .bar sections.

compile: Use also inferior munmap
Currently inferior memory is allocated by inferior mmap() but it is never
deallocated; despite the injected objfile incl. its symbols is freed. This was
intentional so that one can do for example:
inferior:
char *str = "foo";
GDB:
(gdb) compile code str = "bar";
I believe later patches will be needed to introduce full control over keeping
vs. discarding the injected module as being discussed in:
compile: objfiles lifetime UI
https://sourceware.org/ml/gdb/2015-04/msg00051.html
Message-ID: <
20150429135735.GA16974@host1.jankratochvil.net>
https://sourceware.org/ml/gdb/2015-05/msg00007.html
As decided by Phil it is better not to leak inferior pages as users can
workaround the issue above for example by:
(gdb) compile code str = strdup ("bar");
I have checked that in fact gdb/doc/ (written by Phil) already expects the
injected code will be unmapped so that does not need to be changed:
compile code int ff = 5; p = &ff;
In this example, @code{p} would point to @code{ff} when the
@code{compile} command is executing the source code provided to it.
However, as variables in the (example) program persist with their
assigned values, the variable @code{p} would point to an invalid
location when the command exists.

Fix =thread-exited not showing up when detaching (PR 15564)
I sent a patch in 2013 for this (incorrectly named =thread-created):
https://cygwin.com/ml/gdb-patches/2013-06/msg00129.html
Tom Tromey was ok with the change, but suggested to add a test as well.
Then I forgot about this patch until today. So here it is again, with the
corresponding test.
The problem is that the =thread-exited event does not appear when detaching
from a local process. It does appear with remote though. It's not a really
big deal, but I'd like it to be consistent.
Tested with local and remote Linux on my Ubuntu 14.04.

PR 17819: Fix --build-id=tree when using --compress-debug-sections.
When --build-id=tree is selected, gold would schedule a set of
tasks to run to compute md5 hashes in parallel on chunks of the
file. The scheduling was done before the
Write_after_input_sections_task ran, so if we are compressing
debug sections, the output file will change size and be remapped
to a new address, sometimes causing the build id computation to
crash, but even when it doesn't crash, it wouldn't include the
debug information in the hash computation.
This patch delays the scheduling of the md5 tasks until after
Write_after_input_sections_task.
