Using address range map to speedup finding inline stack for address.

* linear search for the top-level DIE
* recursive linear traverse the DIE tree to find the path to the leaf DIE

[GlobalISel] Support vector-of-pointers in LLT

This fixes PR32471.

As comment 10 on that bug report highlights
(https://bugs.llvm.org//show_bug.cgi?id=32471#c10), there are quite a
few different defendable design tradeoffs that could be made, including
not representing pointers at all in LLT.

I decided to go for representing vector-of-pointer as a concept in LLT,
while keeping the size of the LLT type 64 bits (this is an increase from
48 bits before). My rationale for keeping pointers explicit is that on
some targets probably it's very handy to have the distinction between
pointer and non-pointer (e.g. 68K has a different register bank for
pointers IIRC). If we keep a scalar pointer, it probably is easiest to
also have a vector-of-pointers to keep LLT relatively conceptually clean
and orthogonal, while we don't have a very strong reason to break that
orthogonality.  Once we gain more experience on the use of LLT, we can
of course reconsider this direction.

Rejecting vector-of-pointer types in the IRTranslator is also an option
to avoid the crash reported in PR32471, but that is only a very
short-term solution; also needs quite a bit of code tweaks in places,
and is probably fragile. Therefore I didn't consider this the best
option.

It is a protected non-virtual member function called only twice,
both from within the class,
and the removed passed argument in both cases is '*this'.
The reason for the existence of that argument seems to be that
back before r43115 Split was a free function,
so an argument to get '*this' was needed - but now that is no longer the
case.

Xin Tong [Wed, 19 Apr 2017 00:03:36 +0000 (00:03 +0000)]
Allow suppressing host and target info in VersionPrinter

Summary:
VersionPrinter by default outputs information about the Host CPU
and Default target. Printing this information requires linking in
a large amount of data, such as supported target triples as C
strings, which in turn bloats the binary size.

Enable a new CMake option LLVM_VERSION_PRINTER_SHOW_HOST_TARGET_INFO
which controls printing of the host and target info. This allows
the target triple names to be dead-code stripped. This is a nice
win for LLVM clients that wish to minimize their binary size, such
as graphics drivers.

By default this is ON, so there is no change in the default behavior.
Clients who wish to suppress this printing can do so by setting this
option to off via CMake.

A test app on Linux that uses ParseCommandLineOptions() shows a binary
size reduction of 23KB (from 149K to 126K) for a Release build, and 24KB
(from 135K to 111K) in a MinSizeRel build.
