Dan Gohman e1019db658 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.

Dan Gohman 1d548d851a 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.

Ted Kremenek 93668002c4 Restructure CFG builder to have just one visitor path instead of two. The result 
is an algorithm that is much easier to understand and slightly more efficient.
Thanks to Mike Stump for our discussions on the CFGBuilder and his comments that
helped prompt this long needed cleanup.

Evan Cheng 18fe458103 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.

Chris Lattner e03a866b34 these two pieces of code are the same because we always

Dan Gohman 80ca01c466 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.

Chris Lattner e79b2bc088 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.

Bob Wilson 46f079e33f 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.
