Summary:
The current default is to create the preamble on the first reparse, aka
second parse. This is useful for clients that do not want to block when
opening a file because serializing the preamble takes a bit of time.
However, this makes the reparse much more expensive and that may be on the
critical path as it's the first interaction a user has with the source code.
YouCompleteMe currently optimizes for the first code interaction by parsing
the file twice when loaded. That's just unnecessarily slow and this flag
helps to avoid that.

This patch does two things:
1. mem2reg is now run immediately after globalopt. Now that globalopt
can localize variables more aggressively, it makes sense to lower
them to SSA form earlier rather than later so they can benefit from
the full set of optimization passes.
2. More scalar optimizations are run after the loop optimizations in
LTO mode. The loop optimizations (especially indvars) can clean up
scalar code sufficiently to make it worthwhile running more scalar
passes. I've particularly added SCCP here as it isn't run anywhere
else in the LTO pass pipeline.
Mem2reg is super cheap and shouldn't affect compilation time at all. The
rest of the added passes are in the LTO pipeline only so doesn't affect
the vast majority of compilations, just the link step.

It is possible to assign arbitrary integer types to strings.
Sometimes it is the result of missing to_string call or apostrophes.

Full type legalizer that works with all vectors length - from 2 to 16, (i32, i64, float, double).
This intrinsic, for example
void @llvm.masked.scatter.v2f32(<2 x float>%data , <2 x float*>%ptrs , i32 align , <2 x i1>%mask )
requires type widening for data and type promotion for mask.

I believe in one place we were always casting to ExtractValueConstantExpr when we were trying to choose between ExtractValueConstantExpr and InsertValueConstantExpr because of this. But since they have identical layouts this didn't cause any observable problems.

Summary:
Currently, ARMGenSubtargetInfo (from ARM.td) is reaching the limit of 96:
enum : uint64_t {
...
XScale = 95
};
We need to bump the maximum value up to accommodate future changes and/or customized subtarget definitions.

The post-dominance property is not sufficient to guarantee that a restore point
inside a loop is safe.
E.g.,
while(1) {
Save
Restore
if (...)
break;
use/def CSRs
}
All the uses/defs of CSRs are dominated by Save and post-dominated
by Restore. However, the CSRs uses are still reachable after
Restore and before Save are executed.
This fixes PR25824

This case was tested in the linker from code, but not from globals indexing into other globals. The linker currently barfs on this, ncbray volunteered to fix it.

For non padded structs, we can just proceed and deaggregate them.
We don't want ot do this when there is padding in the struct as to not
lose information about this padding (the subsequents passes would then
try hard to preserve the padding, which is undesirable).
Also update extractvalue.ll and cast.ll so that they use structs with padding.
Remove the FIXME in the extractvalue of laod case as the non padded case is
handled when processing the load, and we don't want to do it on the padded
case.

This is a very simple implementation of a thread pool using C++11
thread. It accepts any std::function<void()> for asynchronous
execution. Individual task can be synchronize using the returned
future, or the client can block on the full queue completion.
In case LLVM is configured with Threading disabled, it falls back
to sequential execution using std::async with launch:deferred.
This is intended to support parallelism for ThinLTO processing in
linker plugin, but is generic enough for any other uses.
This is a recommit of r255444 ; trying to workaround a bug in the
MSVC 2013 standard library. I think I was hit by:

find the largest address range (possibly combining multiple
LineEntry's for this line number) that is contiguous.
This allows lldb's fast-step stepping algorithm to potentially
run for a longer address range than if we have to stop at every
LineEntry indicating a subexpression in the source line.

This patch goes through and enables C++11 and C++14 features for newer GCC's.
The main changes are:
1. Turn on variable templates. (Uses __cpp_variable_templates)
2. Assert atomic<Tp> is trivially copyable (Uses _GNUC_VER >= 501).
3. Turn on trailing return support for GCC. (Uses _GNUC_VER >= 404)
4. XFAIL void_t test for GCC 5.1 and 5.2. Fixed in GCC 6.

This is the listener's spawned connection, not the listener itself.
(i.e. this is the test runner's receiving side of test event sockets).
A standard socket.error will just issue an INFO statement and continue.
Something other than a socket.error will get an ERROR: printed (and
also continue).
Hopefully this gets us more info and also handles the completely
to-be-expected scenario that the test inferior might go down at
any point.
