Normally, we need to look through derived-to-base casts when creating
temporary object regions (added in r175854). However, if the temporary
is a pointer (rather than a struct/class instance), we need to /preserve/
the base casts that have been applied.

This also ensures that we really do create a new temporary region when
we need to: MaterializeTemporaryExpr and lvalue CXXDefaultArgExprs.

Fixes PR15342, although the test case doesn't include the crash because
I couldn't isolate it.

With the new support for trivial copy constructors, we are not always
consistent about whether a CXXTempObjectRegion gets reused or created
from scratch, which affects whether qualifiers are preserved. However,
we probably don't care anyway.

This also switches to using the current PrintingPolicy for the type,
which means C++ types don't get a spurious 'struct' prefix anymore.

SymbolFileDWARF code:

  - If a class is being uniqued to another copy of itself
    and the method lists don't match exactly, take a slow
    path and at least unique the methods that they have
    in common.

  - Sort name_to_die maps before querying them.  This
    would otherwise result in uniquing failures because
    looking up a name in a map that contains it would
    often fail.

  - Tolerate classes in other symbol files in the case
    of debugging with .o files rather than with a
    .dSYM.  We used to assume that the classes being
    uniqued were in the same symbol file, causing
    unpredictable results.

This will dramatically reduce the number of cases where
a function does not have a valid DeclContext.

This changes the RecordingMemoryManager in lli to use mapped memory rather than malloc to allocate memory for sections and uses a 'near' MemoryBlock to keep the allocations together.  This works around a problem in MCJIT where relocations are applied to a generated image immediately oupon generation, which isn't appropriate for the remote case.

This addresses a case when we inline a wrong method due to incorrect

family, which creates an instance of another class.

These nodes are never consulted by any analyzer client code, so they are
used only for machinery for removing dead bindings.  Once successor nodes
are generated they can be safely removed.

This greatly reduces the amount of nodes that are generated in some case,
lowering the memory regression when analyzing Sema.cpp introduced by
r176010 from 14% to 2%.

Adding an RST document for cpp11-migrate. This user documentation explains
command line options, transformations, risk level and how it applies to
loop convert, and code examples of transformations.

There is a TODO task under "Risk" for "Loop Convert" to find code examples
that produce incorrect transformations that change semantics. The definition
of risk in loop convert and instances where the confidence level is lowered
will need to be looked at more carefully.

Information for all new features (including verbose output, auto transform)
will be added in a later change.

r175026 added support for default values, but didn't take reference
parameters into account, which expect the default argument to be an
lvalue. Use createTemporaryRegionIfNeeded if we can evaluate the default
expr as an rvalue but the expected result is an lvalue.

Fixes the most recent report of PR12915. The original report predates
default argument support, so that can't be it.

While RegionStore checks to make sure casts on TypedValueRegions are valid,
it does not do the same for SymbolicRegions, which do not have perfect type
info anyway. Additionally, MemRegion::getAsOffset does not take a
ProgramState, so it can't use dynamic type info to determine a better type
for the regions. (This could also be dangerous if the type of a super-region
changes!)

Account for this by checking that a base object region is valid on top of a
symbolic region, and falling back to "symbolic offset" mode if not.

Fixes PR15345.
