205b641954 Change tests from "opt %s" to "opt < %s" so that opt doesn't see the 
input filename so that opt doesn't print the input filename in the
output so that grep lines in the tests don't unintentionally match
strings in the input filename.

6fb64b1b17 Fix PR4948 (and a leak): by not destroying the DwarfException 
object, the timer it creates was not being deleted.  Since the
timer belonged to a static timer group, the timer group would
be destroyed on shutdown, and would notice and complain that
not all timers it contained were destroyed.

316cce5a0f change FnStubs from being a StringMap<std::string> to being a much 
more efficient SmallPtrSet<MCSymbol*>.  This eliminates string
craziness and fixes CodeGen/X86/darwin-quote.ll with the new asmprinter.

Codegen is producing stubs in a nondeterminstic order, but it was doing
this before anyway.

0f5802b4d8 reimplement X86ATTAsmPrinter::GetGlobalAddressSymbol in terms of 
Mangler::getNameWithPrefix.  In addition to avoiding some over
quoting, this also is more efficient because it uses smallvector
instead of std::string thrashing.

36550f7606 add a new Mangler::getNameWithPrefix API which returns the 
(uniqued if unnamed) global variable name with the prefix that
it is supposed to get.  It doesn't do "mangling" in the sense of
adding quotes and hacking on bad characters.

93831c07de It's not legal to fold a load from a narrower stack slot into a wider instruction. If done, the instruction does a 64-bit load and that's not 
safe. This can happen we a subreg_to_reg 0 has been coalesced. One
exception is when the instruction that folds the load is a move, then we
can simply turn it into a 32-bit load from the stack slot.

aa66e3d968 Teach lib/VMCore/ConstantFold.cpp how to set the inbounds keyword and 
how to fold notionally-out-of-bounds array getelementptr indices instead
of just doing these in lib/Analysis/ConstantFolding.cpp, because it can
be done in a fairly general way without TargetData, and because not all
constants are visited by lib/Analysis/ConstantFolding.cpp. This enables
more constant folding.

Also, set the "inbounds" flag when the getelementptr indices are
one-past-the-end.

58a0550024 Factor out the code for checking that all indices in a getelementptr are 
within the notional bounds of the static type of the getelementptr (which
is not the same as "inbounds") from GlobalOpt into a utility routine,
and use it in ConstantFold.cpp to check whether there are any mis-behaved
indices.

9f0fb453d8 Added the ParseInstruction() hook for target specific assembler directives so 
that things like .word can be parsed as target specific.  Moved parsing .word
out of AsmParser.cpp into X86AsmParser.cpp as it is 2 bytes on X86 and 4 bytes
for other targets that support the .word directive.
