This rule permits the injected-class-name of a class template to be used as
both a template type argument and a template template argument, with no extra
syntax required to disambiguate.

This patch adds support for codegen of 'target parallel' on the host.
It is also the first combined directive that requires two or more
captured statements.  Support for this functionality is included in
the patch.

A combined directive such as 'target parallel' has two captured
statements, one for the 'target' and the other for the 'parallel'
region.  Two captured statements are required because each has
different implicit parameters (see SemaOpenMP.cpp).  For example,
the 'parallel' has 'global_tid' and 'bound_tid' while the 'target'
does not.  The patch adds support for handling multiple captured
statements based on the combined directive.

When codegen'ing the 'target parallel' directive, the 'target'
outlined function is created using the outer captured statement
and the 'parallel' outlined function is created using the inner
captured statement.

This is just wasted space, we don't support state points from multiple

instead of the ones in the diag state.

The idea for this originated from a really tricky bug: ISRs on ARM don't
automatically save off the VFP regs, so if say, memcpy gets interrupted and the
ISR itself calls memcpy, the regs are left clobbered when the ISR is done.

Python bindings cannot support Python 3 without work being done to fix Unicode c-string conversion.

This was attempted in https://reviews.llvm.org/D26082. That patch was reverted due to memory access issues on Linux.

This revision fixes enough language compatibility issues for the clang module to be loaded and raise an error if the Python version is not 2.

The rules around typechecking deduced template arguments during partial
ordering are not clear, and while the prior behavior does not seem to be
correct (it doesn't follow the general model of partial ordering where each
template parameter is replaced by a non-dependent but unique value), the new
behavior is also not clearly right and breaks some existing idioms.

The new behavior is retained for dealing with non-type template parameters
with 'auto' types, as without it even the most basic uses of that feature
don't work. We can revisit this once CWG has come to an agreement on how
partial ordering with 'auto' non-type template parameters is supposed to
work.

Summary: Change r291428 introduced ASI detection after closing curly braces. That would generally be correct, however this breaks indentation for structural statements. What happens is that CompoundStatementIndenter increases indentation for the current line, then after reading ASI creates a new line (with the increased line level), and only after the structural parser sees e.g. the if/then/else branch closed, line level is reduced. That leads to the new line started by ASI having a level too high.
