an external layout is used
Summary:
The patch removes alignment of virtual bases when an external layout is used.
We have two cases:
- the external layout source has an information about virtual bases offsets,
so we just use them;
- the external source has no information about virtual bases offsets. In this
case we can't predict where the base will be located. If we will align it but
there will be something like `#pragma pack(push, 1)` really, then likely our
layout will not fit into the real structure size, and then some asserts will
hit. The asserts look reasonable, so I don't think that we need to remove
them. May be it would be better instead don't align fields / bases etc.
(so treat it always as `#pragma pack(push, 1)`) when an external layout source
is used but no info about a field location is presented.
This one is related to D49871

This reverts commit r345004, as it broke tests when actually run
on windows; see e.g.
http://lab.llvm.org:8011/builders/clang-x64-windows-msvc/builds/763.
This broke tests that had captured a variable containing a path
with backslashes, which failed to match cases in the output
where the path separators had been changed into forward slashes.
llvm-svn: 345005
libtool inspects the output of $CC -v to detect what object files and
libraries are linked in by default. When clang is built as a native
windows executable, all paths are formatted with backslashes, and
the backslashes cause each argument to be enclosed in quotes. The
backslashes and quotes break further processing within libtool (which
is implemented in shell script, running in e.g. msys) pretty badly.
Between unix style pathes (that only work in tools that are linked
to the msys runtime, essentially the same as cygwin) and proper windows
style paths (with backslashes, that can easily break shell scripts
and msys environments), the best compromise is to use windows style
paths (starting with e.g. c:) but with forward slashes, which both
msys based tools, shell scripts and native windows executables can
cope with. This incidentally turns out to be the form of paths that
GCC prints out when run with -v on windows as well.
This change potentially makes the output from clang -v a bit more
inconsistent, but it is isn't necessarily very consistent to begin with.

Since multiversion variant functions can be inline, in C they become
available-externally linkage. This ends up causing the variants to not
be emitted, and not available to the linker.
The solution is to make sure that multiversion functions are always
emitted by marking them linkonce.

Summary:
Partial revert of r330873 ('[Driver] Reland "Android triples are not
aliases for other triples."')
While we don't want `-target *-linux-android` to alias to non
*-linux-android libs and binaries, it turns out we do want the
opposite. Ie. We would like for `-target *-linux-gnu` to still be
able to use *-android libs and binaries.
In fact, this is used to cross assemble and link the Linux kernel for
Android devices.
`-target *-linux-gnu` needs to be used for the Linux kernel when
using the android binutils prebuilts (*-linux-android).
The use of `-target *-linux-android` on C source files will cause
Clang to perform optimizations based on the presence of bionic (due to
r265481 ('Faster stack-protector for Android/AArch64.')) which is
invalid within the Linux kernel and will produce a non-bootable kernel
image.
Of course, you could just use the standard binutils (*-linux-gnu),
but Android does not distribute these. So this patch fixes a problem
that only occurs when cross assembling and linking a Linux kernel with
the Android provided binutils, which is what is done within Android's
build system.

This removes the primary remaining API producing `TerminatorInst` which
will reduce the rate at which code is introduced trying to use it and
generally make it much easier to remove the remaining APIs across the
codebase.
Also clean up some of the stragglers that the previous mechanical update
of variables missed.
Users of LLVM and out-of-tree code generally will need to update any
explicit variable types to handle this. Replacing `TerminatorInst` with
`Instruction` (or `auto`) almost always works. Most of these edits were
made in prior commits using the perl one-liner:
```
perl -i -ple 's/TerminatorInst(\b.* = .*getTerminator\(\))/Instruction\1/g'

This also my break some rare use cases where people overload for both
