That is slightly more convinent as allows to store pointer on
program header entry in a more safe way.

This is PR32112. Previously when we linked executable with
--unresolved-symbols=ignore-all and undefined symbols, like:
_start:
callq und@PLT
we did not create relocations, though it looks in that case
we should delegate handling of such symbols to runtime linker,
hence should emit them. Patch fixes that.

With this we only ask LTO to keep a C named section if there is a
__start_ or __end symbol.
This is not as strict as lld's --gc-sections, but is as good as we can
get without having a far more detailed ir summary.

This patch fixes a small issue with respect to how memory region names
are parsed on output section descriptions. For example, consider:
.text : { *(.text) } > rom
That can also be written like:
.text : { *(.text) } >rom
The latter form is accepted by GNU LD and is fairly common.

Also handle overflow correctly in LDR/STR relocations. Even if the
offset range of a 8 byte LDR instruction is 15 bit (even if the immediate
itself is 12 bit) due to a 3 bit shift, only include up to 12 bits of offset
after doing the relocation, by limiting the range of the immediate by the
number of shifted bits.

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.
llvm-svn: 309002
Also emit an error if /manifestinput: is used without /manifest:embed.
Increases compatibility with link.exe

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.

The same adjustment is already done for the entry point in
Writer.cpp and for relocations that point to executable code
in Chunks.cpp.

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.
