Bill, could you take a look at this? I don't have a checkout of compiler-rt that builds. It seems obviously-correct to me, but I wish it did a compare against cur_buffer_size to make sure it's in range.

Hi, I've been seeing a crash in llvm_gcda_emit_arcs() on x86_64. The crash occurs executing a movdqa instruction with an unaligned src address. The attached patch to the compiler-rt project fixes the problem by using memcpy() to read data from the write_buffer[] in GCDAProfiling.c. This is my first patch submission to llvm so please let me know if I've missed any steps. I'm not on
