case where realpath() fails. When this occurs we segfault trying to
create a std::string from a NULL pointer.

Fixes PR5635.

Kill off clang/win32 which contains the hand generated Visual Studio project files. These files are severely out of date and have been superseded by the CMake build system. RIP.

Don't call Decl::CollectingStats(false) and Stmt::CollectingStats(false). When called with false these functions return whether statistics are enabled. They don't change any state. Since we're not using the return value avoid calling them in the first place.

function names outside of templates - they'll probably cause some damage there as
they're largely untested.

Move LLVM backend options to explicit clang-cc / clang -cc1 options, which we then manually pass to the command line library; eventually the latter grossness should be fixed by a real API when creating the target machine.

which we now compile to one load in the loop:

	movsd	%xmm0, 8(%rsi,%rax,8)
	incq	%rax
	cmpq	%rcx, %rax
	jne	LBB1_2

instead of:
