Eric Christopher 27e7ffc7d4 Partial code for emitting thread local bss data.

Chris Lattner 8ca2fd2e93 just add a fixme for the StructuredArgs leak, it shouldn't affect 
c++'03 code and variadic support "needs work".

Chris Lattner 047f5aa007 switch TemplateArgumentListBuilder to hold its flat argument list in a smallvector 
instead of new[]'d.  This greatly reduces the number of new[]'s, and guess what, 
they were all leaked.

This adds a fixme in this hunk:

   unsigned NumPackArgs = NumFlatArgs - PackBeginIndex;
+  // FIXME: NumPackArgs shouldn't be negative here???
   if (NumPackArgs)
-    PackArgs = &FlatArgs[PackBeginIndex];
+    PackArgs = FlatArgs.data()+PackBeginIndex;

where test/SemaTemplate/variadic-class-template-2.cpp is accessing the vector
out of range and NumPackArgs is negative.  I assume variadic template args are
completely hosed.

Chris Lattner ce7a22d97c fix the TemplateArgumentList copy constructor to not 
be a copy constructor (since it isn't one semantically)
and fix the ownership bits it sets to be correct!

Chris Lattner c9b03bcc5d Clarify TemplateArgumentList ownership over its "flat" and 
"structure" arg lists, the first step to fixing some massive
memory leaks.

Dan Gohman 20fab456da Teach LSR how to cope better with unrolled loops on targets where 
the addressing modes don't make this trivially easy. This allows
it to avoid falling into the less precise heuristics in more
cases.

Bob Wilson 42603958fb Optimize away insertelement of an undef value. This shows up in 
test/Codegen/ARM/reg_sequence.ll but it doesn't affect the generated code
because the coalescer cleans it up.  Radar 7998853.

Douglas Gregor fa6010b6e4 When a conditional operator is an rvalue of class type, we need to 
create a temporary copy of both the "true" and "false" results. Fixes
the Boost.Interprocess failures.

Daniel did all the hard work of tracking down the issue, I get to type
up the trivial fix for this horrible miscompile.

Jakob Stoklund Olesen e0eddb21f5 Add support for partial redefs to the fast register allocator. 
A partial redef now triggers a reload if required. Also don't add
<imp-def,dead> operands for physical superregisters.

Kill flags are still treated as full register kills, and <imp-use,kill> operands
are added for physical superregisters as before.

Jakob Stoklund Olesen 5d4c134a94 Add MachineInstr::readsVirtualRegister() in preparation for proper handling of 
partial redefines.

We are going to treat a partial redefine of a virtual register as a
read-modify-write:

  %reg1024:6 = OP

Unless the register is fully clobbered:

  %reg1024:6 = OP, %reg1024<imp-def>

MachineInstr::readsVirtualRegister() knows the difference. The first case is a
read, the second isn't.

Bob Wilson 6a1bfd282b When expanding a vector_shuffle, the element type may not be legal and may 
need to be promoted.  The BUILD_VECTOR and EXTRACT_VECTOR_ELT nodes generated
here already allow the promoted type to be used without further changes, so
just do the promotion.  This fixes part of pr7167.

Daniel Dunbar d2f78e755f MC/X86: Lower TAILCALLd[64] to JMP_1, to allow relaxation and to avoid same 
prefix byte problem as in r104062.
 - As a total hack to keep the TAILCALL markers in the output, which some tests depend on, this invents a new TAILJMP_1 instruction.

Chandler Carruth 8fd2b8935e Provide a naming class for UnresolvedLookupExprs, even when occuring on 
template names. We were completely missing naming classes for many unqualified
lookups, but this didn't trigger code paths that need it. This removes part of
an optimization that re-uses the template name lookup done by the parser to
determine if explicit template arguments actually form a template-id.
Unfortunately the technique for avoiding the duplicate lookup lost needed data
such as the class context in which the lookup succeeded.
