On Darwin, it is required to stamp the object file with VERSION_MIN load
command. This commit will provide a VERSRION_MIN load command to the
MachO file that doesn't specify the version itself by inferring from
Target Triple.

Since r241097, `DIBuilder` has only created distinct `DICompileUnit`s.
The backend is liable to start relying on that (if it hasn't already),
so make uniquable `DICompileUnit`s illegal and automatically upgrade old
bitcode. This is a nice cleanup, since we can remove an unnecessary
`DenseSet` (and the associated uniquing info) from `LLVMContextImpl`.
Almost all the testcases were updated with this script:
git grep -e '= !DICompileUnit' -l -- test |
grep -v test/Bitcode |
xargs sed -i '' -e 's,= !DICompileUnit,= distinct !DICompileUnit,'
I imagine something similar should work for out-of-tree testcases.

This commit broke the build. Numerous build bots broken, and it was
blocking my progress so reverting.
It should be trivial to reproduce -- enable the BPF backend and it
should fail when running llvm-tblgen.

Bitpatterns rejected by the decoder method of `MSR (immediate)` should be
decoded as the `extended MSR (register)` instruction.

Summary:
- Signed 16-bit should have priority over unsigned.
- For la, unsigned 16-bit must use ori+addu rather than directly use ori.
- Correct tests on 32-bit immediates with 64-bit predicates by
sign-extending the immediate beforehand. For example, isInt<16>(0xffff8000)
should be true and use addiu.
Also split li/la testing into separate files due to their size.

In this patch I have only encoding. Intrinsics and DAG lowering will be in the next patch.
I temporary removed the old intrinsics test (just to split this patch).
Half types are not covered here.

Don't let the disassembler pick call <.text> if a function happens to
live at the start of the section by only using function symbols.

Correctly support assembling "pushw $imm8" on x86-64 targets.
Also some cleanup of the PUSH instructions (PUSH64i16 and PUSHi16 actually
represent the same instruction)
This fixes PR23996

The test part of r241149 has been reverted in r241451, due to misplaced test cases.
This patch splits those test cases among the appropriate targets.

This patch teaches the AsmParser to accept add/adds/sub/subs/cmp/cmn
with a negative immediate operand and convert them as shown:
add Rd, Rn, -imm -> sub Rd, Rn, imm
sub Rd, Rn, -imm -> add Rd, Rn, imm
adds Rd, Rn, -imm -> subs Rd, Rn, imm
subs Rd, Rn, -imm -> adds Rd, Rn, imm
cmp Rn, -imm -> cmn Rn, imm
cmn Rn, -imm -> cmp Rn, imm
Those instructions are an alternate syntax available to assembly coders,
and are needed in order to support code already compiling with some other
assemblers (gas). They are documented in the "ARMv8 Instruction Set
Overview", in the "Arithmetic (immediate)" section. This makes llvm-mc
a programmer-friendly assembler !
This also fixes PR20978: "Assembly handling of adding negative numbers
not as smart as gas".

Only consider an instruction a candidate for relaxation if the last operand of the
instruction is an expression. We previously checked whether any operand is an expression,
which is useless, since for all instructions concerned, the only operand that may be
affected by relaxation is the last one.
In addition, this removes the check for having RIP as an argument, since it was
plain wrong - even when one of the arguments is RIP, relaxation may still be needed.
This fixes PR9807.
