Douglas Gregor 031296e316 Kill off two more uses of Sema::CheckReferenceInit in favor of the new
initialization code. Exposed a bug where we were not marking an
implicit conversion as an lvalue when we were forming a call to a
conversion function whose return type is a reference.

Evan Cheng b07a29ecd4 Disable folding loads into tail call in 32-bit PIC mode. It can introduce illegal code like this:
addl    $12, %esp
        popl    %esi
        popl    %edi
        popl    %ebx
        popl    %ebp
        jmpl    *__Block_deallocator-L1$pb(%esi)  # TAILCALL

The problem is the global base register is assigned GR32 register class. TCRETURNmi needs the registers making up the address mode to have the GR32_TC register class.

The *proper* fix is for X86DAGToDAGISel::getGlobalBaseReg() to return a copy from the global base register of the machine function rather than returning the register itself. But that has the potential of causing it to be coalesced to a more restrictive register class: GR32_TC. It can introduce additional copies and spills. For something as important the PIC base, it's not worth it especially since this is not an issue on 64-bit.

Chris Lattner ddca7b09f7 revert 99444/99445. This doesn't cause the failure of
2006-07-19-stwbrx-crash.ll for me, but it's the only likely
patch in the blame list of several bots.  Lets see if this
fixes it.

Douglas Gregor deb714ceeb Switch static_cast from the old reference-initialization code (via
CheckReferenceInit) over to the new initialization code
(InitializationSequence), which is better-tested and doesn't require
us to compute the entire conversion sequence twice.

Douglas Gregor 02dde146e0 When returning from a function that has a reference return type, use

Rafael Espindola 1dbd474f2e Discussing with dgregor we decided that we should not force the emission of
implicit methods on explicit template instantiation definitions. As a
consequence, we should emit them at every use, even if we see a explicit
template instantiation declaration.

This is already the current behaviour, but it is good to test for that :-)

Torok Edwin 4bbfdd41ea Fix memory leak in liveintervals: the destructor for VNInfos must be called,
otherwise the SmallVector it contains doesn't free its memory.
In most cases LiveIntervalAnalysis could get away by not calling the destructor,
because VNInfos are bumpptr-allocated, and smallvectors usually don't grow.
However when the SmallVector does grow it always leaks.

This is the valgrind shown leak from the original testcase:
