e3c6222c76 [X86][SSE] Sign extension for target vector sizes less than 128 bits (pt1)
This patch adds support for sign extension for sub 128-bit vectors, such as to v2i32. It concatenates with UNDEF subvectors up to 128-bits, performs the sign extension (i.e. as v4i32) and then extracts the target subvector.

Patch 1/2 of D10589 - the second patch covers the conversion of v2i8/v2i16 to v2f64.

6890be345e Fix an overly aggressive assertion in getCopyFromPartsVector.
The assertion in getCopyFromPartsVector assumed that the vector 'part' must
match the type of argument (arguments are potentially split into multiple
parts). However, in some cases the targets return a 'part' of the right size
but with a different type. We already handle this case correctly later on
and generate a bitcast. This commit just makes sure that we are actually
checking the property that we care about.

516286ff69 Use function attribute "trap-func-name" and remove TargetOptions::TrapFuncName.
This commit changes normal isel and fast isel to read the user-defined trap
function name from function attribute "trap-func-name" attached to llvm.trap or
llvm.debugtrap instead of from TargetOptions::TrapFuncName. This is needed to
use clang's command line option "-ftrap-function" for LTO and enable changing
the trap function name on a per-call-site basis.

Out-of-tree projects currently using TargetOptions::TrapFuncName to specify the
trap function name should attach attribute "trap-func-name" to the call sites
of llvm.trap and llvm.debugtrap instead.

397fac95d5 [PPC64LE] Remove implicit-subreg restriction from VSX swap removal
In r241285, I removed the SUBREG_TO_REG restriction from VSX swap
removal, determining that this was overly conservative.  We have
another form of the same restriction in that we check for the presence
of implicit subregs in vector operations.  As with SUBREG_TO_REG for
partial register conversions, an implicit subreg is safe in and of
itself, provided no other operation makes a lane-sensitive assumption
about the result.  This patch removes that restriction, by removing
the HasImplicitSubreg flag and all code that relies on it.

I've added a test case that fails to optimize before this patch is
applied, and optimizes properly with the patch.  Test based on a
report from Anton Blanchard.

a5a5a62fff [PPC64LE] Teach swap optimization about the doubleword splat idiom
With a previous patch, the VSX swap optimization is able to recognize
the doubleword load-splat idiom that can be implemented using lxvdsx.
However, that does not cover a doubleword splat where the source is a
register.  We can implement this using xxspltd (a special form of
xxpermdi).  This patch teaches the swap optimization pass about this
idiom.

As a prerequisite, it also permits swap optimization to succeed for
all forms of SUBREG_TO_REG.  Previously we were conservative and only
allowed SUBREG_TO_REG when it copied a full register.  However, on
reflection any form of SUBREG_TO_REG is safe in and of itself, so long
as an unsafe operation is not performed on its result.  In particular,
a widening SUBREG_TO_REG often occurs as an input to a doubleword
splat idiom, particularly in auto-vectorized code.

The doubleword splat idiom is an XXPERMDI operation where both source
registers are identical, and the selection mask is either 0 (splat the
first element) or 3 (splat the second element).  To determine whether
the registers are identical, we use the existing mechanism for looking
through "copy-like" operations.  That mechanism has a side effect of
marking the XXPERMDI operation as using a physical register, which
would invalidate its presence in a swap-optimized region.  This is
correct for the form of XXPERMDI that performs a swap and hence would
be removed, but is not what we want for a doubleword-splat variety of
XXPERMDI.  Therefore we reset the physical-register flag on the
XXPERMDI when it represents a splat.

A simple test case is added to verify that we generate the splat and
that we also remove the xxswapd instructions that would otherwise be
associated with the load and store of another operand.

479dc2c0fe [Support] Lazy load of dbghlp.dll on Windows
This patch changes linkage with dbghlp.dll for clang from static (at load time)
to on demand (at the first use of required functions). Clang uses dbghlp.dll
only in minor use-cases. First of all in case of crash and in case of plugin load.
The dbghlp.dll library can be absent on system. In this case clang will fail
to load. With lazy load of dbghlp.dll clang can work even if dbghlp.dll
is not available.

8992bae990 [GraphWriter] Don't wait on xdg-open when not on Apple.
By default, the GraphWriter code assumes that the generic file open
program (`open` on Apple, `xdg-open` on other systems) can wait on the
forked proces to complete. When the fork ends, the code would delete
the temporary dot files created, and return.

On GNU/Linux, the xdg-open program does not have a "wait for your fork
to complete before dying" option. So the behaviour was that xdg-open
would launch a process, quickly die itself, and then the GraphWriter
code would think its OK to quickly delete all the temporary files.
Once the temporary files were deleted, the dot viewers would get very
upset, and often give you weird errors.

This change only waits on the generic open program on Apple platforms.
Elsewhere, we don't wait on the process, and hence we don't try and
clean up the temporary files.

c6f1b8a4ba [LazyCallGraph] Port test case from r240039 to LCG.
Summary:
r240039 adds a test case to check that CallGraph does the right thing
with respect to non-leaf intrinsics like statepoint and patchpoint.
This ports the same test case to LazyCallGraph.  LazyCallGraph already
does the right thing with respect to escaping function pointers so there
is no need to change any code.
