fe529a2c29 Revert 76177 for now. It's messing up ARM asm printing. Also this significant debate about its efficiency.

e45061eefe Convert more code to use Operator instead of explicitly handling both 
ConstantExpr and Instruction. This involves duplicating some code
between GetElementPtrInst and GEPOperator, but it's not a lot.

93cbd452ed Make BasicAliasAnalysis and Value::getUnderlyingObject use 
GEPOperator's hasNoPointer0verflow(), and make a few places in instcombine
that create GEPs that may overflow clear the NoOverflow value. Among
other things, this partially addresses PR2831.

67ccedff04 Fix x86 inline ams 'q' constraint support. In 32-bit mode, it's just like 'Q', i.e. EAX, EDX, ECX, EBX. In 64-bit mode, it just means all the i64r registers. Yeah, that makes sense.

b6cede976e these two pieces of code are the same because we always

eh_frame_common labels.

25a722cc45 Add a new Operator class, for handling Instructions and ConstantExprs 
in a convenient manner, factoring out some common code from
InstructionCombining and ValueTracking. Move the contents of
BinaryOperators.h into Operator.h and use Operator to generalize them
to support ConstantExprs as well as Instructions.

ffe0c407be Untangle a snarl that I discovered when updating the mangler, 
starting in getCurrentFunctionEHName.  Among other problems,
we would try to privative a "foo.eh" label, but end up emitting
the label as _Lfoo.eh instead of L_foo.eh on darwin.  This is really
bad, and the linker has always tolerated these labels existing.
For now, just emit them as _foo.eh.

This patch also fixes problems with ".eh" labels on unnamed
functions and eliminates two strangely defined TargetAsmInfo
hooks.

7c323a8936 Fix a crash in SROA. The FunctionPass::doInitialization method was never 
being called so that Context was never initialized.  I'm not sure if this
is the right fix but at least it keeps opt from crashing.
