This fixes builds that use cmake, which automatically sets CXX to
/usr/bin/CC by default.

Fix the VCVT instruction. It must round towards zero when converting from
a floating-point to an integer value. This was not the case causing issues
when printing certain values.
There is a VCVTR instruction that will round depending on the current
rounding mode. We don't yet support this instruction, or setting the
rounding mode.
The header_length field is the number of bytes following the field to
the first byte of the line number program. The hard-coded constants
previously here (4 + 2 + 4) were correct only for 32-bit DWARF.

re-removes the printing of size for non-regular files, supports
type-less root (.) entries as seen in a couple ports, and corrects a bug
in -N that caused expanded Subversion $FreeBSD$ strings in comments to
be processed as /etc/group entries.
Includes one trivial portability fix (including <stdint.h> in three
files) that has been submitted upstream but not yet committed.

runtime by the dynamic linker, check for their equality in libcxxrt by
not only comparing the typeinfo's name pointers, but also comparing the
full names, if necessary. (This is similar to what GNU libstdc++ does
in its default configuration.) The 'deep' check can be turned off again
by defining LIBCXXRT_MERGED_TYPEINFO, and recompiling libcxxrt.

X86: Don't fold spills into SSE operations if the stack is unaligned.
Regalloc can emit unaligned spills nowadays, but we can't fold the
spills into SSE ops if we can't guarantee alignment. PR12250.
This fixes unaligned SSE accesses (leading to a SIGBUS) which could
occur in the ffmpeg ports.

Remove invalid assert in DAGTypeLegalizer::RemapValue
There is a comment at the top of DAGTypeLegalizer::PerformExpensiveChecks
which, in part, says:
// Note that these invariants may not hold momentarily when processing a node:
// the node being processed may be put in a map before being marked Processed.
Unfortunately, this assert would be valid only if the above-mentioned invariant
held unconditionally. This was causing llc to assert when, in fact,
everything was fine.
Thanks to Richard Sandiford for investigating this issue!
Fixes PR16562.

On MIPS .dynamic is read-only and so a special section .rld_map is used
to store the pointer to the rtld information for debuggers. This
section had a hard coded size of 4 bytes which is not correct for
mips64. (Note that FreeBSD's rtld does not yet populate .rld_map.)

The X86FixupLEAs pass for Intel Atom must not call
convertToThreeAddress on ADD16rr opcodes, if src1 != src, since that
would cause convertToThreeAddress to try to create a virtual register.
This is not permitted after register allocation, which is when the
X86FixupLEAs pass runs.
This patch fixes PR16785.

ISelDAG: spot chain cycles involving MachineNodes
Previously, the DAGISel function WalkChainUsers was spotting that it
had entered already-selected territory by whether a node was a
MachineNode (amongst other things). Since it's fairly common practice
to insert MachineNodes during ISelLowering, this was not the correct
check.
Looking around, it seems that other nodes get their NodeId set to -1
upon selection, so this makes sure the same thing happens to all
MachineNodes and uses that characteristic to determine whether we
should stop looking for a loop during selection.
This should fix PR15840.
Specifically, this fixes the long-standing assertion failure when
compiling the multimedia/gstreamer port on i386. Thanks to Tijl
Coosemans for his help in getting upstream to fix it.
