Use the uniform single line C++/99 style for code comments.
This is part of the cleanup proposed in "[RFC] compiler-rt builtins
cleanup and refactoring".

to reflect the new license. These used slightly different spellings that
defeated my regular expressions.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

avoid libm dependencies when possible.
Summary:
The complex division builtins (div?c3) use logb methods from libm to scale numbers during division and avoid rounding issues. However, these come from libm, meaning anyone that uses --rtlib=compiler-rt also has to include -lm. Implement logb* methods for standard ieee 754 floats so we can avoid -lm on those platforms, falling back to the old behavior (using either logb() or `__builtin_logb()`) when not supported.
These new methods are defined internally as `__compiler_rt_logb` so as not to conflict with the libm definitions in any way.
This fixes just the libm methods mentioned in PR32279 and PR28652. libc is still required, although that seems to not be an issue.
Note: this is proposed as an alternative to just adding -lm: D49330.

cl does not support C99 completely as of VS2015. Emulate _Complex to allow
building with MSVC.
