[Support] Propagate the environment into the test child process

Should fix the dragonegg bootstrap builder, which reasonably needs
LD_LIBRARY_PATH to be set.

Changed back (relative to commit 179786) the operations executed when extract(cast) is transformed to cast(extract). It uses the Builder class as before. In addition the result node is added to the Worklist, so all the previous extract users will become the new scalar cast users.

Add a missing reference on a std::vector<> out param

Pointed out by Eli.  The test passes for me either way, so I missed
this.

Optimize MachineBasicBlock::getSymbol by caching the symbol. Since the symbol
name computation is expensive, this helps save about 25% of the time spent in
this function.

[ms-inline asm] Add the OpDecl to the InlineAsmIdentifierInfo struct and in turn
the MCParsedAsmOperand.

[ms-inline asm] Removed this unnecessary check.  In the current implementation,
Disp will always be one of MCSymbolRefExpr or MCConstantExpr, and never NULL.

Move C++ code out of the C headers and into either C++ headers
or the C++ files themselves. This enables people to use
just a C compiler to interoperate with LLVM.

Remove unused DwarfSectionOffsetDirective string

The value isn't actually used, and setting it emits a COFF specific
directive.

Struct-path aware TBAA: update getMostGenericTBAA 

The tag is of type TBAANode when flag EnableStructPathTBAA is off.

Move implementation of MDNode::getMostGenericTBAA to TypeBasedAliasAnalysis.cpp
since it depends on how to interprete the MDNodes for scalar TBAA and
struct-path aware TBAA.
