This change enables building builtins for multiple different targets
using LLVM runtimes directory.
To specify the builtin targets to be built, use the LLVM_BUILTIN_TARGETS
variable, where the value is the list of targets. To pass a per target
variable to the builtin build, you can set BUILTINS_<target>_<variable>
where <variable> will be passed to the builtin build for <target>.

This reverts commit r260386.
These tests all pass for me locally. I have no idea if they will pass on all configurations, so I'll watch the bots closely.

incorrect output when LLVM is built with `LLVM_BUILD_LLVM_DYLIB`.
`llvm-config` previously produced output like this
```
$ llvm-config --libfiles
/usr/lib/liblibLLVM-4.0svn.so.so
$ llvm-config --libnames
liblibLLVM-4.0svn.so.so
```
The library prefix and shared library extension were added to
the library name twice which was wrong.
I wanted to write a test cases for this but it looks like **all**
`llvm-config` tests were disabled by r260386 so I'll leave this for
now.

This reverts r289215 (git SHA1 cb7b86a1). It breaks the ubsan build
because a DenseMap that keys off of `AssertingVH<T>` will hit UB when it
tries to cast the empty and tombstone keys to `T *` (due to insufficient
alignment).
This is the relevant stack trace (thanks to Mike Aizatsky):

I'm transitioning away from my current employer, and I do not foresee myself
spending much time on LLDB in the near future. Ideally somebody on the Google
Android team takes over the gdb-remote protocol tests, and somebody with decent
familiarity with the test suite infrastructure takes over the parallel test
runner and test event stream portions of the Python test suite.

Sort the headers by name before adding the includes in
collectModuleHeaderIncludes. This makes the include order for building
umbrellas deterministic across different filesystems and also guarantees
that the ASTWriter always dump top headers in the same order.
There's currently no good way to test for this behavior.

Power8 has MTVSRWZ but no LXSIBZX/LXSIHZX, so move 1 or 2 bytes to VSR through MTVSRWZ is much faster than store the extended value into stack and load it with LXSIWZX.

Summary:
I looked at libgcc's implementation (which is based on the paper,
Software for Doubled-Precision Floating-Point Computations", by Seppo Linnainmaa,
ACM TOMS vol 7 no 3, September 1981, pages 272-283.) and made it generic to
arbitrary IEEE floats.

This patch ensures the correct minimum bit width during type-shrinking.
Previously when type-shrinking, we always sign-extended values back to their
original width. However, if we are going to sign-extend, and the sign bit is
unknown, we have to increase the minimum bit width by one bit so the
sign-extend will fill the upper bits correctly. If the sign bit is known to be
zero, we can perform a zero-extend instead. This should fix PR31243.

DWARF specifies that "line 0" really means "no appropriate source
location" in the line table. By default, use this for branch targets
and some other cases that have no specified source location, to
prevent inheriting unfortunate line numbers from physically preceding
instructions (which might be from completely unrelated source).
Updated patch allows enabling or suppressing this behavior for all
unspecified source locations.

Certain source control systems like to set the read-only bit on their files,
which interferes with opening "test.dat" for both input and output.
Fortunately, we can work around this without losing test coverage.
Now, the ifstream.cons tests have comments referring to the ofstream.cons tests.
There, we're creating writable files (not checked into source control),
where the ifstream constructor tests will succeed.
Fixes D26814.

I'm planning on changing the way we load metadata to enable laziness.
I'm getting lost in this gigantic files, and gigantic class that is the bitcode
reader. This is a first toward splitting it in a few coarse components that
are more easily understandable.

Collect the necessary input PCH files.
Do not try to validate the AST before copying it out because if the
crash is in this path, we won't be able to collect it. Instead only
check if it's a file containg an AST.

Summary:
Compiling with GCC 5 or later can fail with a bogus error "constructor
required before non-static data member for
llvm::ValueEnumerator::MDRange::First has been parsed".
This was originally fixed upstream in GCC PR 70528, but later this fix
was reverted, and released versions of GCC still show the bogus error.
To work around this, replace MDRange's declaration of a default
constructor with a definition.
