[NFC] Factor out + document build requirements

Summary: This change factors out compiler checking / warning, and documents 
LLVM_FORCE_USE_OLD_TOOLCHAIN. It doesn't introduce any functional changes nor 
policy changes, these will come late.

Bump minimum toolchain version

Summary:
The RFC on moving past C++11 got good traction:
  http://lists.llvm.org/pipermail/llvm-dev/2019-January/129452.html

This patch therefore bumps the toolchain versions according to our policy:

[cmake] Pass LLVM_TEMPORARILY_ALLOW_OLD_TOOLCHAIN to NATIVE configure

We should propagate this down to host builds so that e.g. people using
an optimized tablegen can do the sub-configure successfully.

-from the `LLVM releases web site `_.
+lld is a high-performance linker that supports ELF (Unix), COFF (Windows),
+Mach-O (macOS), MinGW and WebAssembly. lld is command-line-compatible with
+GNU linkers and Microsoft link.exe and is significantly faster than the
+system default linkers.
