(Re-apply patch after bug fixing)
This diff makes sure that the driver does not pass
-fomit-frame-pointer or -momit-leaf-frame-pointer to
the frontend when -pg is used. Currently, clang gives
an error if -fomit-frame-pointer is used in combination
with -pg, but -momit-leaf-frame-pointer was forgotten.
Also, disable frame pointer elimination in the frontend
when -pg is set.

Runtime library requires, that codegen for 'depend' clause for 'out' dependency kind must be the same as codegen for 'depend' clause with 'inout' dependency.

If AS of a variable/parameter declaration is not set by the source,
OpenCL v2.0 s6.5 defines explicit rules for default ASes:
- The AS of global and local static variables defaults to global;
- All pointers point to generic AS.

the case where a specific range is replaced by new text. Previously,
the calculation would shift any position from within a replaced region
to the first character after the region. This is undersirable, e.g. for
clang-format's include sorting.

The pointer returned by __RTDynamicCast must be bitcasted. However, it
was not expected that __RTDynamicCast would be invoked, resulting in the
bitcast occuring in a different BasicBlock than the invoke. This caused
a down-stream PHI to get confused about which BasicBlock the incomming
value was from.
This fixes PR25606.

Cross compiling from linux and OSX results in Error: Exec format.
This is because the linker is expecting ELF formated objects.
By passing the target we can explicitly tell the linker that
it should be linking COFF objects regardless of the host.

Specifying a fixed triple is not possible because that target may not
even be compiler. Go for a simpler fix by using a _? regex for the
prefix.

This adds support for three types of argument specifications for bootstrap builds:
(1) Arguments prefixed with BOOTSTRAP_* will be passed through with the leading BOOTSTRAP_ removed.
(2) CLANG_BOOTSTRAP_PASSTHROUGH can specify a list of variables to be passed through as they are set.
(3) BOOTSTRAP_DEFAULT_PASSTHROUGH is a list of some default passthrough variables that are always passed through. Those variables include the version string and should only specify variables that are always expected to be the same between the stage1 and stage2

When passing around CMake arguments as lists of arguments any arguments containing lists need to have their semi-colons escaped otherwise CMake will split the arguments in the middle.

This allows us to construct Linux toolchains without a valid linker. This
is needed for example to build a CUDA device toolchain after r253385.

This is similar to the earlier fix I did, r253702, expect that here it
is function names that are being searched for. If the function name
matches part of the directory name it can cause an apparent test
case failure.

Rather than storing BeforeInfo in the DenseMap by value, this stores a
unique_ptr to it, so that we can keep a pointer to it live across
subsequent DenseMap insertions.
This change also removes the unique_ptr wrapper around BeforeVect
because now we're indirecting at a higher level.

Summary: The frontend debuginfo tests should not invoke llvm passes which includes add-discriminators that will change the debug info generated by FE.

This patch adds support of #pragma vtordisp inside functions in attempt to improve compatibility. Microsoft compiler appears to save the stack of vtordisp modes on entry of struct methods' bodies and restore it on exit (method-local vtordisp).
