namespaces by name given an optional symbol context. I might end up
dressing up the "clang::NamespaceDecl" into a lldb_private::Namespace
class if we need to do more than is currenlty required of namespaces.
Currently we only need to be able to lookup a namespace by name when
parsing expressions, so I kept it simple for now. The idea here is
even though we are passing around a "clang::NamespaceDecl *", that
we always have it be an opaque pointer (it is forward declared inside
of "lldb/Core/ClangForward.h") and we only use clang::NamespaceDecl
implementations inside of ClangASTContext, or ClangASTType when we need
to extract information from the namespace decl object.

of the enumerators rather than the actual expressible range. This is
great when dealing with opaque *values* of that type, but when computing
the range of the type for purposes of converting *into* it, it produces
warnings in cases we don't care about (e.g. enum_t x = 500;). Divide
the logic into these two cases and use the more conservative range for
targets.

NEON vector types need to be mangled in a special way to comply with ARM's ABI,
similar to some of the AltiVec-specific vector types. This patch is mostly
just renaming a bunch of "AltiVecSpecific" things, since they will no longer
be specific to AltiVec. Besides that, it just adds the new "NeonVector" enum.

references. For example, this allows gvn to eliminate the load in
this example:
void foo(int n, int* p, int *q) {
p[0] = 0;
p[1] = 1;
if (n) {
*q = p[0];
}
}

in the order they occur within the class template, delaying
out-of-line member template partial specializations until after the
class has been fully instantiated. This fixes a regression introduced
by r118454 (itself a fix for PR8001).

Whenever splitting wants to insert a copy, it checks if the value can be
rematerialized cheaply instead.
Missing features:
- Delete instructions when all uses have been rematerialized.
- Truncate live ranges to the remaining uses after rematerialization.

benchmarks hitting an assertion.
Adds LiveIntervalUnion::collectInterferingVRegs.
Fixes "late spilling" by checking for any unspillable live vregs among
all physReg aliases.

nodes can be used in loops, this could result in infinite looping
if there is no recursion limit, so add such a limit. It is also
used for the SelectInst case because in theory there could be an
infinite loop there too if the basic block is unreachable.
