George Rimar aa3541875e [ELF] - Store PhdrEntry values by pointers instead of storing by value.
That is slightly more convinent as allows to store pointer on

George Rimar 678188d48b [ELF] - Fix missing relocation when linking executable with --unresolved-symbols=ignore-all
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.

Rui Ueyama acd632d338 Add {Obj,Import,Bitcode}File::Instances to COFF input files.
We did the same thing for ELF in r309152, and I want to maintain
COFF and ELF as close as possible.

Rafael Espindola be28c2e4a5 Add --gc-sections to a test.
This shows that the logic in --gc-sections is a bit more precise than
what can be easily done in LTO.

Rafael Espindola 4b075bb218 Make __start_sec __end_sec handling more precise.
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.

Meador Inge b0e6229742 [ELF, LinkerScript] Memory region name parsing fix
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.

Martin Storsjo 38608c0975 [COFF, ARM64] Handle ADRP immediate offsets in relocations
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

output file whenever it is still usable",
and we may want to handle other cases too.
