Added pragma(llvmdc, "string") for misc per-module compiler configuration, currently "string" can only be "verbose" which forces -vv for module it appears in. Reimplemented support for nested functions/class using a new approach. Added error on taking address of intrinsic. Fixed problems with the ->syntaxCopy of TypeFunction delegate exp. Removed DtoDType and replaced all uses with ->toBasetype() instead. Removed unused inplace stuff. Fixed a bunch of issues in the runtime unittests, not complete yet. Added mini tests.

After making sure llvmdc and its runtime are up to date, use
./runtest tmp-sensible-name
to run tests for llvmdc.
Move into reference/ subfolder and add to svn if desired.

Use
./findregressions old-test-resultfile tmp-sensible-name
to find changes.

Recommended for comparing to DMD:
./findregressions reference/dmd-version llvmdc-something | grep -v "PASS -> XFAIL" | sort > tmp-new-regressions
