Previously, only -1 and +1 step values are supported for induction variables. This patch extends LV to support
arbitrary constant steps.
Initial patch by Alexey Volkov. Some bug fixes are added in the following version.

Fatal errors disable all further diagnostics.  Continuing to permit
template instantiation does nothing but make it take longer for clang to
finish with the TU.

Instead, halt all further instantiation.

Fixed in PR22396.

[AArch64]Fix PR21675, a bug about lowering llvm.ctpop.i32. We should noot use "DAG.getUNDEF(MVT::v8i8)" to get all zero vector.

SimpleFileWrapper was a class to wrap an existing (possibly non-mutable)
file as a mutable file. We used instances of the class in RoundTrip*
passes, because the passes convert mutable files to non-mutable files,
and we needed to convert them back to mutable.

That feature can be implemented without defining a new class. Generally
speaking, if we can implement a feature without defining a class and
using only public interface of exsiting classes, that's preferred way
to do that. And this is the case.

accumulateAndSortLibcalls in LTOCodeGenerator.cpp collects names of runtime
library functions which are used to identify user-defined functions that should
be protected. Previously, this function would only scan the TargetLowering
object belonging to the "main" subtarget for the library function names. This
commit changes it to scan all per-function subtargets.

In the large code model, we now put __chkstk in %r11 before calling it.

Refactor the code so that we only do this once. Simplify things by using
__chkstk_ms instead of __chkstk on cygming. We already use that symbol
in the prolog emission, and it simplifies our logic.

Second half of PR18582.
