Refactor the Args class.
There were a number of issues with the Args class preventing
efficient use of strings and incoporating LLVM's StringRef class.
The two biggest were:
1. Backing memory stored in a std::string, so we would frequently
have to use const_cast to get a mutable buffer for passing to
various low level APIs.
2. backing std::strings stored in a std::list, which doesn't
provide random access.
I wanted to solve these two issues so that we could provide
StringRef access to the underlying arguments, and also a way
to provide range-based access to the underlying argument array
while still providing convenient c-style access via an argv style
const char**.
The solution here is to store arguments in a single "entry" class
which contains the backing memory, a StringRef with precomputed
length, and the quote char. The backing memory is a manually
allocated const char* so that it is not invalidated when the
container is resized, and there is a separate argv array provided
for c-style access.

[lit] Use argparse instead of optparse
Summary:
optparse is deprecated in Python 2.7, which is the minimum version of
Python required to run the LLVM test suite. Replace its usage in lit
with argparse, optparse's 2.7 replacement module.
argparse has several benefits over optparse, but this commit does not
make use of those benefits yet. Instead, it simply uses the new API,
and attempts to keep the number of changes to a minimum.
Confirmed that lit's test suite, as well as LLVM's regression test suite,
still pass with these changes.

[lit] Compare to None using identity, not equality
Summary:
In Python, `None` is a singleton, so checking whether a variable is
`None` may be done with `is` or `is not`. This has a slight advantage
over equiality comparisons `== None` and `!= None`, since `__eq__` may
be overridden in Python to produce sometimes unexpected results.
Using `is None` and `is not None` is also recommended practice in
https://www.python.org/dev/peps/pep-0008:
> Comparisons to singletons like `None` should always be done with `is` or
> `is not`, never the equality operators.

[PowerPC] Account for the ELFv2 function prologue during branch selection
The PPC branch-selection pass, which performs branch relaxation, needs to
account for the padding that might be introduced to satisfy block alignment
requirements. We were assuming that the first block was at offset zero (i.e.
had the alignment of the function itself), but under the ELFv2 ABI, a global
entry function prologue is added to the first block, and it is a
two-instruction sequence (i.e. eight-bytes long). If the function has 16-byte
alignment, the fact that the first block is eight bytes offset from the start
of the function is relevant to calculating where padding will be added in
between later blocks.
Unfortunately, I don't have a small test case.

* Correctly translate between file and buffer positions using bufferpos-to-filepos (if available) or a fallback.
* Don't invoke the shell, it's not necessary and adds complexity.
* Save clang-rename output in a buffer and display that on failure.
* Save all buffers before calling clang-rename. This is required anyway and prevents data loss when the buffer is later reverted.

[PowerPC] Refactor soft-float support, and enable PPC64 soft float
This change enables soft-float for PowerPC64, and also makes soft-float disable
all vector instruction sets for both 32-bit and 64-bit modes. This latter part
is necessary because the PPC backend canonicalizes many Altivec vector types to
floating-point types, and so soft-float breaks scalarization support for many
operations. Both for embedded targets and for operating-system kernels desiring
soft-float support, it seems reasonable that disabling hardware floating-point
also disables vector instructions (embedded targets without hardware floating
point support are unlikely to have Altivec, etc. and operating system kernels
desiring not to use floating-point registers to lower syscall cost are unlikely
to want to use vector registers either). If someone needs this to work, we'll
need to change the fact that we promote many Altivec operations to act on
v4f32. To make it possible to disable Altivec when soft-float is enabled,
hardware floating-point support needs to be expressed as a positive feature,
like the others, and not a negative feature, because target features cannot
have dependencies on the disabling of some other feature. So +soft-float has
now become -hard-float.
Fixes PR26970.
