CodeGen: generate single libcall for fptrunc -> f16 operations.
Previously we asserted on this code. Currently compiler-rt doesn't
actually implement any of these new libcalls, but external help is
pretty much the only viable option for LLVM.
I've followed the much more generic "__truncST2" naming, as opposed to
the odd name for f32 -> f16 truncation. This can obviously be changed
later, or overridden by any targets that need to.

X86: support double extension of f16 type.
x86 has no native ability to extend an f16 to f64, but the same result
is obtained if we expand it into two separate extensions: f16 -> f32
-> f64.
Unfortunately the same is not true for truncate, so that still results
in a compilation failure.

CodeGen: extend f16 conversions to permit types > float.
This makes the two intrinsics @llvm.convert.from.f16 and
@llvm.convert.to.f16 accept types other than simple "float". This is
only strictly needed for the truncate operation, since otherwise
double rounding occurs and there's no way to represent the strict IEEE
conversion. However, for symmetry we allow larger types in the extend
too.
During legalization, we can expand an "fp16_to_double" operation into
two extends for convenience, but abort when the truncate isn't legal. A new
libcall is probably needed here.
Even after this commit, various target tweaks are needed to actually use the
extended intrinsics. I've put these into separate commits for clarity, so there
are no actual tests of f64 conversion here.

[mips] Correct ELF e_flags for the N32 ABI when using a mips-* triple rather than a mips64-* triple
Summary:
Generally speaking, mips-* vs mips64-* should not be used to make decisions
about the content or format of the ELF. This should be based on the ABI
and CPU in use. For example, `mips-linux-gnu-clang -mips64r2 -mabi=64`
should produce an ELF64 as should `mips64-linux-gnu-clang -mabi=64`.
Conversely, `mips64-linux-gnu-clang -mabi=n32` should produce an ELF32 as
should `mips-linux-gnu-clang -mips64r2 -mabi=n32`.
This patch fixes the e_flags but leaves the ELF32 vs ELF64 issue for now
since there is no apparent way to base this decision on the ABI and CPU.

The cpr1_size field describes the minimum register width to run the program

Summary:
With this patch (and a corresponding LLVM patch), assembling an empty file with

differences are:
* GCC/GAS produce objects have a .pdr section
* GCC/GAS produce objects have a .gnu.attributes section

of strings in the string table.

`<experimental/utility>` only contains `class erased_type`.
This patch also updates the documentation to list the `erased_type` class as "initial implementation complete".
Test Plan:
Three test cases where added:
1. Test that `_LIBCPP_VERSION` is defined.
2. Test that `<utility>` has been included.
3. Test that `erased_type` is in the correct namespace and is constexpr default constructible.
