5ac8547a41 Use subword loads instead of a 4-byte load when the size of a structure (or a 
piece of it) that is being passed by value is smaller than a word.

fb23462889 Add NativeClient operating system support. 
This patch adds support of NativeClient (*-*-nacl) OS support to LLVM.
It's already supported in autoconf/config.sub.

The motivation for this change is to start upstreaming PNaCl work. The
whole set of patches include llvm backends (i686, x86_64, ARM),
llvm-gcc (probably, would not be upstreamed because it's deprecated)
and clang (the work has been just started, the amount of changes is
going to be low and the most of the work is expected to be done close
to the mainline).

78affc9ea1 STC2L_POST and STC2L_POST should be handled the same as STCL_POST/LDC_POST for the purposes of decoding all operands except the predicate. 
Found by randomized testing.

857fd8fcda Update autoconfig/config.{sub,guess} to the latest version 
from the GNU upstream: git://git.savannah.gnu.org/config.git

1. It eliminates a local LLVM patch for auroraux (because, the
mainline config.sub has already got support of auroraux)
2. It adds several new recognized target cpus and operating systems
(in particular, PNaCl)

90b5a08e1f ARM Thumb blx instruction fixup has same data range as bl. 
These fixups are handled poorly in general, and should have a single
contiguous range of bits per fixup type, but that's not how they're
currently organized, so for now in complex ones like for blx, we just tell the
emitter it's OK for the fixup to munge any bit it wants.
