6fb0c1e474 Convert more tests over to the new atomic instructions.
I did not convert Atomics-32.ll and Atomics-64.ll by hand; the diff is autoupgrade output.

The wmb test is gone because there isn't any way to express wmb with the new atomic instructions; if someone really needs a non-asm way to write a wmb on Alpha, a platform-specific intrisic could be added.

2056d15bd9 Also match negative offsets for addrmode3 and addrmode5.
Math is hard, and isScaledConstantInRange() always returned false for
negative constants.  It was doing unsigned division of negative numbers
before casting back to signed.

5e6b65cf0d Do not unnecessarily use AT_specification DIE because it does not add any value.
Few weeks ago, llvm completely inverted the debug info graph. Earlier each debug info node used to keep track of its compile unit, now compile unit keeps track of important nodes. One impact of this change is that the global variable's do not have any context, which should be checked before deciding to use AT_specification DIE.

011be52871 test/CodeGen/X86/avx-minmax.ll: Unbreak Win32.
On Windows x64, 128-bit arguments are not passed by reg but by indirect. eg.

maxpd:
        vmovapd (%rcx), %xmm0
        vmaxpd  (%rdx), %xmm0, %xmm0

FIXME: I don't care YMM on x64 for now.

8586e62d91 ARM isel bug fix for adds/subs operands.
Modified ARMISelLowering::AdjustInstrPostInstrSelection to handle the
full gamut of CPSR defs/uses including instructins whose "optional"
cc_out operand is not really optional. This allowed removal of the
hasPostISelHook to simplify the .td files and make the implementation
more robust.

7ae11279e9 When promoting integer vectors we often create ext-loads. This patch adds a
dag-combine optimization to implement the ext-load efficiently (using shuffles).

For example the type <4 x i8> is stored in memory as i32, but it needs to
find its way into a <4 x i32> register. Previously we scalarized the memory
access, now we use shuffles.

f2b8c854dd Synthesize x86 max/min instructions also for vectors (i.e. produce
maxps and maxpd).  This broke the sse41-blend.ll testcase by causing
maxpd to be produced rather than a cmp+blend pair, which is the reason
I tweaked it.  Gives a small speedup on doduc with dragonegg when the
GCC vectorizer is used.

fa1ca3070b Change all checks regarding the presence of any SSE level to always
take into consideration the presence of AVX. This change, together with
the SSEDomainFix enabled for AVX, makes AVX codegen to always (hopefully)
emit the same code as SSE for 128-bit vector ops. I don't
have a testcase for this, but AVX now beats SSE in performance for
128-bit ops in the majority of programas in the llvm testsuite
