The specified rounding mode will be used and restored
to what it was before the test ran.
Additionally, it moves ForceRoundingMode and RoundingMode
out of MPFRUtils to be used in more places.

Previously, the entire support/CPP folder was in one header library,
which meant that a lot of headers were included where they shouldn't be.
This patch splits each header into its own target, as well as adjusting
each place they were included to only include what is used.

CMAKE_CXX_STANDARD 14 is set in the llvm-project/llvm folder overriding all COMPILE_OPTIONS -std=c++17. We need to override the CXX_STANDARD property of the target in order to set the correct C++ standard flags.

The idea is to move all pieces related to the actual libc sources to the
"src" directory. This allows downstream users to ship and build just the
"src" directory.

Some ctype functions are called from other libc functions (e.g. isspace
is used in atoi). By moving ctype_utils.h to __support it becomes easier
to include just the implementations of these functions. For these
reasons the implementation for isspace was moved into
ctype_utils as well.
FPUtils was moved to simplify the build order, and to clarify which
files are a part of the actual libc.
Many files were modified to accomodate these changes, mostly changing
the #include paths.

Included more math functions to Windows's entrypoints
and made a cmake option (-DLLVM_LIBC_MPFR_INSTALL_PATH)
where the user can specify the install path where the MPFR
library was built so it can be linked. The try_compile was
moved to LLVMLibCCheckMPFR.cmake, so the variable that is
set after this process can retain its value in other files
of the same parent file. A direct reason for this is for
LIBC_TESTS_CAN_USE_MPFR to be true when the user specifies
MPFR's path and retain its value even after leaving the file.

This class is to serve as a replacement for llvm::StringRef as part of
the plans to limit dependency on other parts of LLVM. One use of
llvm::StringRef in MPFRWrapper has been replaced with the new class.

A new utils library named 'fputil' is added. This library is used in
math tests and the MPFR wrapper. The math implementations will be
modified to use this library in a later round.

NFC intended in the implementaton. Only mechanical changes to fit the LLVM
libc implementation standard have been done.
Math testing infrastructure has been added. This infrastructure compares the
results produced by the libc with the high precision results from MPFR.
Tests making use of this infrastructure have been added for cosf, sinf and
sincosf.
