lib/Object/ELFObjectFile.cpp: Fix undefined behavior for MC/ELF/many-section.s not to fail (on msvc).

DenseMap::lookup(k) would return "default constructor value" when k was not met. It would be useless when value type were POD.

of namespaces (only in the modules where they've
been found) for entities inside those namespaces.

For each NamespaceDecl that has been imported into
the parser, we maintain a map containing
[ModuleSP, ClangNamespaceDecl] pairs in the ASTImporter.
This map has one entry for each module in which the
namespace has been found.  When we later scan for an
entity inside a namespace, we search only the modules
in which that namespace was found.

Also made a small whitespace fix in 
ClangExpressionParser.cpp.

1. The speculation check may not have been performed if the BB hasn't had a load
   LICM candidate.
2. If the candidate would be CSE'ed, then go ahead and speculatively LICM the
   instruction even if it's in high register pressure situation.

When widening a copy, we are reading a larger register that may not be
live.  Use an <undef> flag to tell the register scavenger and machine
code verifier that we know the value isn't defined.

We now widen:

  %S6<def> = COPY %S4<kill>, %D3<imp-def>

into:

  %D3<def> = VMOVD %D2<undef>, pred:14, pred:%noreg, %S4<imp-use,kill>

This also keeps the <kill> flag on %S4 so we don't inadvertently kill a
live value in %S5.

Finally, ensure that ARMBaseInstrInfo::setExecutionDomain() preserves
the <undef> flag when converting VMOVD to VORR.

before running the benchmarking logic.  An example,

./dotest.py -v -t +b -k 'process attach -n Mail' -k 'thread backtrace all' -p TestRunHooksThenSteppings.py

spawns lldb, attaches to the 'Mail' application, does a backtrace for all threads, and then
runs the benchmark to step the inferior multiple times.

significant regression for should-this-be-a-call fixits,
and to repair some such regression from the introduction of

try to build calls appropriately.  Harden the build-a-call
