This patch enables us to use the existing `libc` support for string conversion functions on the GPU. This required setting the `fenv_t` and long double configuration. As far as I am aware, long doubles are converted to doubles on the GPU and the floating point environment is just an `uint32_t`. This code is still untested as we are still working out how to run the unit tests on the GPU. Reviewed By: michaelrj Differential Revision: https://reviews.llvm.org/D149306

The following functions and headers are supported at least partially on the
|
|
device. Some functions are implemented fully on the GPU, while others require a
|
|
`remote procedure call <libc_gpu_rpc>`.
