[ValueTracking] Extend range metadata to call/invoke
Summary:
With this patch, range metadata can be added to call/invoke including
IntrinsicInst. Previously, it could only be added to load.
Rename computeKnownBitsLoad to computeKnownBitsFromRangeMetadata because
range metadata is not only used by load.
Update the language reference to reflect this change.
Test Plan:
Add several tests in range-2.ll to confirm the verifier is happy with
having range metadata on call/invoke.
Add two tests in AddOverFlow.ll to confirm annotating range metadata to
call/invoke can benefit InstCombine.

Emit DWARF3 call frame information when DWARF3+ debug info is requested
Currently, llvm always emits a DWARF CIE with a version of 1, even when emitting
DWARF 3 or 4, which both support CIE version 3. This patch makes it emit the
newer CIE version when we are emitting DWARF 3 or 4. This will not reduce
compatibility, as we already emit other DWARF3/4 features, and is worth doing as
the DWARF3 spec removed some ambiguities in the interpretation of call frame
information.
It also fixes a minor bug where the "return address" field of the CIE was
encoded as a ULEB128, which is only valid when the CIE version is 3. There are
no test changes for this, because (as far as I can tell) none of the platforms
that we test have a return address register with a DWARF register number >127.

When looking at the 64-bit SVR4 indirect call sequence, I noticed
an unnecessary load of r12. And indeed the code says:
// R12 must contain the address of an indirect callee.
But this is not correct; in the 64-bit SVR4 (ELFv1) ABI, there is
no need to load r12 at this point. It seems this code and comment
is a remnant of code originally shared with the Darwin ABI ...
This patch simply removes the unnecessary load.

[PowerPC] Simplify and improve loading into TOC register
During an indirect function call sequence on the 64-bit SVR4 ABI,
generate code must load and then restore the TOC register.
This does not use a regular LOAD instruction since the TOC
register r2 is marked as reserved. Instead, the are two
special instruction patterns:
let RST = 2, DS = 2 in
def LDinto_toc: DSForm_1a<58, 0, (outs), (ins g8rc:$reg),
"ld 2, 8($reg)", IIC_LdStLD,
[(PPCload_toc i64:$reg)]>, isPPC64;
let RST = 2, DS = 10, RA = 1 in
def LDtoc_restore : DSForm_1a<58, 0, (outs), (ins),
"ld 2, 40(1)", IIC_LdStLD,
[(PPCtoc_restore)]>, isPPC64;
Note that these not only restrict the destination of the
load to r2, but they also restrict the *source* of the
load to particular address combinations. The latter is
a problem when we want to support the ELFv2 ABI, since
there the TOC save slot is no longer at 40(1).
This patch replaces those two instructions with a single
instruction pattern that only hard-codes r2 as destination,
but supports generic addresses as source. This will allow
supporting the ELFv2 ABI, and also helps generate more
efficient code for calls to absolute addresses (allowing
simplification of the ppc64-calls.ll test case).

[PowerPC] Do not use BLA with the 64-bit SVR4 ABI
The PowerPC back-end uses BLA to implement calls to functions at
known-constant addresses, which is apparently used for certain
system routines on Darwin.
However, with the 64-bit SVR4 ABI, this is actually incorrect.
An immediate function pointer value on this platform is not
directly usable as a target address for BLA:
- in the ELFv1 ABI, the function pointer value refers to the
*function descriptor*, not the code address
- in the ELFv2 ABI, the function pointer value refers to the
global entry point, but BL(A) would only be correct when
calling the *local* entry point
This bug didn't show up since using immediate function pointer
values is not usually done in the 64-bit SVR4 ABI in the first
place. However, I ran into this issue with a certain use case
of LLVM as JIT, where immediate function pointer values were
uses to implement callbacks from JITted code to helpers in
statically compiled code.
Fixed by simply not using BLA with the 64-bit SVR4 ABI.

[AArch64] Fix a pattern match failure caused by creating improper CONCAT_VECTOR.
ReconstructShuffle() may wrongly creat a CONCAT_VECTOR trying to
concat 2 of v2i32 into v4i16. This commit is to fix this issue and
try to generate UZP1 instead of lots of MOV and INS.
Patch is initalized by Kevin Qin, and refactored by Tim Northover.

Allow X86FastIsel to cope with 64 bit absolute relocations
This patch is a follow up to r211040 & r211052. Rather than bailing out of fast
isel this patch will generate an alternate instruction (movabsq) instead of the
leaq. While this will always have enough room to handle the 64 bit displacment
it is generally over kill for internal symbols (most displacements will be
within 32 bits) but since we have no way of communicating the code model to the
the assmebler in order to avoid flagging an absolute leal/leaq as illegal when
using a symbolic displacement.

[FastISel][X86] Optimize predicates and fold CMP instructions.
This optimizes predicates for certain compares, such as fcmp oeq %x, %x to
fcmp ord %x, %x. The latter one is more efficient to generate.
The same optimization is applied to conditional branches.

Remove more occurrences of the unused-mutex-parameter pattern.
This pattern loses some of its usefulness when the mutex type is
statically polymorphic as opposed to runtime polymorphic, as
swapping out the mutex type requires changing a significant number
of function parameters, and templatizing the function parameter
requires the methods to be defined in the headers.
Furthermore, if LLVM is compiled with threads disabled then there
may even be no mutex to acquire anyway, so it should not be up to
individual APIs to know whether or not acquiring a mutex is required
to use those APIs to begin with. It should be up to the user of the
API.

Add "-format darwin" to llvm-size to be like darwin's size(1) -m output, and
and the -l option for the long format. Also when the object is a Mach-O
file and the format is berkeley produce output like darwin’s default size(1)
summary berkeley derived output.
Like System V format, there are also some small changes in how and where
the file names and archive member names are printed for darwin and
Mach-O.
Like the changes to llvm-nm these are the first steps in seeing if it is
possible to make llvm-size produce the same output as darwin's size(1).
