Hi,

This patch merges the D front-end impleentation with upstream dmd
f8a1a5153, and the D runtime library with upstream druntime 2b5c0b27.

Adds a new test directive COMPILABLE_MATH_TEST, and support has been
added for it in gdc-convert-test so that they are skipped if phobos is
not present on the target.

Only change in D runtime is a small documentation fix.

Bootstrapped and regression tested on x86_64-linux-gnu, committed to
mainline.

Regards
Iain.
