ELF/ARM: Ignore R_ARM_V4BX for ARMv4 but allow linking
This patch allow the ARM relocation R_ARM_V4BX to be processed by lld,
although it is not really handled in the static relocation code. The
relocation is in the form:
Relocation section '.rel.text' at offset 0x428 contains 4 entries:
Offset Info Type Sym.Value Sym. Name
00000014 00000028 R_ARM_V4BX
Meaning it does have a direct target, but rather references to an absolute
section *ABS* (in this exemple to the .text segment itself). It makes the
target Atom after file parse to not have a associated pointer and thus
generating a derrefence NULL point in ELFFile<ELFT>::findAtom. Current
approach is just ignore and return nullptr in such cases.
The problem relies that default GCC configuration
for arm-linux-gnueabi{hf} emits the relocation for the asm:
--
.syntax unified
.arm
.p2align 2
.type fn, %function
fn:
ldr r3, .LGOT
ldr r2, .LGOT+4
.LPIC:
add r3, pc, r3
ldr r2, [r3, r2]
cmp r2, #0
bxeq lr
b __start__
.LGOT:
.word _GLOBAL_OFFSET_TABLE_-(.LPIC+8)
.word __start__(GOT)
--
But only with the option -march=armv4 (which is the default GCC configuration).
For arm5 and forward the relocation is not created. This a special relocation
(defined miscellaneous for ARM) that instruct the linker to replace the bx
instruction into a mov. GNU linker has some options related to which substitution
it can create for such cases.
With this patch I can dynamically link an application against a GLIBC
arm-linux-gnueabi system configured with default GCC.

This patch makes that change.

it is hexadecimal while the other two are decimal.

IR: Add assembly/bitcode support for function metadata attachments
Add serialization support for function metadata attachments (added in
r235783). The syntax is:
define @foo() !attach !0 {
Metadata attachments are only allowed on functions with bodies. Since
they come before the `{`, they're not really part of the body; since
they require a body, they're not really part of the header. In
`LLParser` I gave them a separate function called from `ParseDefine()`,
`ParseOptionalFunctionMetadata()`.
In bitcode, I'm using the same `METADATA_ATTACHMENT` record used by
instructions. Instruction metadata attachments are included in a
special "attachment" block at the end of a `Function`. The attachment
records are laid out like this:
InstID (KindID MetadataID)+
Note that these records always have an odd number of fields. The new
code takes advantage of this to recognize function attachments (which
don't need an instruction ID):
(KindID MetadataID)+
This means we can use the same attachment block already used for
instructions.

On targets with a scaling factor on the offset of the LOAD/STORE operations, the
