a94c339423 [MC/Mach-O] Add support for linker options in Mach-O files.

398db9368d Complete the existing support of ARM v6m, v7m, and v7em, i.e., respectively cortex-m0, cortex-m3, and cortex-m4 on the backend side.
Adds new subtype values for the MachO format and use them when the related triple are set.

97defc37d6 Fix misaligned access in MachO object file reader: despite containing an
int64_t, Symbol64TableEntry is actually only stored with 4-byte alignment
within the file.

The usage of #pragma pack here is copied from the corresponding code in
Support/Endian.h, so shouldn't introduce any new portability problems.

3e96531186 Refactor data-in-code annotations.
Use a dedicated MachO load command to annotate data-in-code regions.
This is the same format the linker produces for final executable images,
allowing consistency of representation and use of introspection tools
for both object and executable files.

Data-in-code regions are annotated via ".data_region"/".end_data_region"
directive pairs, with an optional region type.

data_region_directive := ".data_region" { region_type }
region_type := "jt8" | "jt16" | "jt32" | "jta32"
end_data_region_directive := ".end_data_region"

The previous handling of ARM-style "$d.*" labels was broken and has
been removed. Specifically, it didn't handle ARM vs. Thumb mode when
marking the end of the section.

f3eb3bba16 Completed :lower16: / :upper16: support for movw / movt pairs on Darwin.
- Fixed :upper16: fix up routine. It should be shifting down the top 16 bits first.
- Added support for Thumb2 :lower16: and :upper16: fix up.
- Added :upper16: and :lower16: relocation support to mach-o object writer.
