[roll] Roll third_party/llvm-libc/src [libc] add modified Eisel-Lemire for long doubles

The Eisel-Lemire algorithm is an effecient way to handle converting to
floating point numbers from strings, but in its base form it only
supports up to 64 bit floating point numbers. This adds an
implementation to handle long doubles.
