Previously we handled this option implicitly, only
for infering unresolved symbols handling policy.
ld man says: "--noinhibit-exec Retain the executable
output file whenever it is still usable",
and we may want to handle other cases too.

This is PR30422,
previously LLD did not render all option aliases in --help.
With this patch it will.

The test used /manifestinput: without /manifest:embed, which isn't actually
supported. Just remove this part of the test for now; if it's important to
check this the llvm-readobj part should be extended to check this.

Also emit an error if /manifestinput: is used without /manifest:embed.

Previously .init_array/.fini_array sections
were not unique and we had 3 .init_array sections +
3 .fini_array input sections passed to linker,
instead of 5 + 5.

This is PR33714.
Previously for each input section offset of memory region
was incremented on a size of output section.
That resulted in a wrong error message saying about
overflow. Patch fixes that.

We were not looking at Repl and so thinking there was no output
section associated with the merged symbol. Because of that it was
produced as absolute.
This was found by an internal round of testing.

SHF_GROUP flag should have been removed when the control reaches here
because InputSectionBase turns the flag off. So this code should be
redundant.

Summary:
If the linker is invoked with `--chroot /foo` and `/bar/baz.o`, it
tries to read the file from `/foo/bar/baz.o`. This feature is useful
when you are dealing with files created by the --reproduce option.

Fix issues found in existing code, while reviewing other changes.
Change the data type of a variable to uint32_t, to avoid potential issues

This fixes cases on ARM64 when importing from more than one DLL,
in case the imports from the first DLL ended up unaligned.
When fixing up a IMAGE_REL_ARM64_PAGEOFFSET_12L, which shifts the
offset by the load/store size, check that the shift doesn't discard
any bits. (This would also detect if the import address chunks were
unaligned.)

With that in place we can use lld's own infrastructure for the low
level detail of dwarf parsing.
With this we don't decompress sections twice, we don't scan all
realocations and even with this simplistic implementation linking
clang with gdb index goes from 34.09 seconds to 20.80 seconds.

In addition this includes a change to prefer symbols with a default
version @@ over unversioned symbols.
Original commit message:
[ELF] - Handle symbols with default version early.
This fixes last testcase provided in PR28414.
In short issue is next: when we had X@@Version symbol in object A,
we did not resolve it to X early. Then when in another object B
we had reference to undefined X, symbol X from archive was fetched.
Since both archive and object A contains another symbol Z, duplicate
symbol definition was triggered as a result.
Correct behavior is to use X@@Version from object A instead and do not fetch
any symbols from archive.

This test is folded into implib-name. Don't bother with the racy test.
The use of %T results in left-overs from previous tests which write out
the same import library as this test.
llvm-svn: 308409
Improve the link conformance for the import name embedded into the
import library. This requires the associated change to the LLVM portion
for the DEF file parser. The import file generation embeds a different
name based on whether the driver is invoked as "link" or "lib".
Furthermore, the LIBRARY keyword in the DEF file influences the import
name. The behaviour can be summarised according to the following table:
| LIBRARY w/ ext | LIBRARY w/o ext | no LIBRARY
-----+----------------+---------------------+------------------
LINK | {value} | {value}.{.dll/.exe} | {output name}
LIB | {value} | {value}.dll | {output name}.dll
