Don't allow multiple line entries with the same address to exist sequentially.
The compiler, when JIT'ing code, can emit illegal DWARF line tables (address is line table sequences must increase). This changes fixes that issue by replacing previous line entries whose start address is the same with the new line entry to avoid having multiple line entries with the same address. Since the address range of lines entries is determined by the delta between the current and next line entry, this shouldn't cause any issues.

When emitting optimization remarks, we test for the presence of

[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

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.

Fix bug in code for avoiding dynamic initialization of dllimport globals
When instantiating dllimport variables with dynamic initializers, don't
bail out of Sema::InstantiateVariableInitializer without calling
PopExpressionEvaluationContext().
This was causing a stale object to stay on the ExprEvalContexts stack,
causing subsequent calls to getCurrentMangleNumberContext() to fail,

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.

Retry building modules that were compiled by other instances and are out-of-date
When another clang instance builds a module, it may still be considered
"out of date" for the current instance in a couple of cases*. This
patch prevents us from giving spurious errors when compilers race to
build a module by allowing the module load to fail when the pcm was
built by a different compiler instance.
* Cases where a module can be out of date despite just having been
built:
1) There are different -I paths between invocations that result in
finding a different module map file for some dependent module. This is
not an error, and should never be diagnosed.
<rdar://problem/
16843887>
2) There are file system races where the headers making up a module are
touched or moved. Although this can sometimes mean trouble, diagnosing
it only during a build-race is worse than useless and we cannot detect
this in general. It is more robust to just rebuild. This was causing
spurious issues in some setups where only the modtime of headers was
bumped during a build.

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.

Fix up lldb cmake linker flags for MacOSX.
Change r210035 broke the Darwin cmake build. The
initial change was intended to stop the --start-group/--end-group
linker flags from being passed to non-gcc/clang-looking compilers,
stopping MSVC from warning on linking. That change, however,
caused MacOSX cmake-based builds to start using the --start-group/
--end-group flags, even though the MacOSX linker doesn't support
them. That broke the MacOSX clang build.
The fix keeps the newer check for a gcc-compatible compiler, but
specifically excludes MacOSX.
