0515a0bb85 drd: Set up red zone before the first instruction of a thread is run. 
Avoids that DRD sporadically reports mysterious false positive conflicting accesses on
amd64 like e.g. the following:

630f8b2e62 Add a configure test for detecting whether gcc supports atomic operations on 
64-bit integers on 32-bit platforms. Apparently newer gcc versions support
this but older versions not. Thanks to Philippe Waroquiers for reporting this.

084b7cb10b Fix #284384 (clang 3.1 -Wunused-value warnings in valgrind.h, 
memcheck.h) by changing a bunch of VALGRIND_DO_CLIENT_REQUEST_EXPR
into VALGRIND_DO_CLIENT_REQUEST_STMT for cases where the return value
of the former would be unused.  (Bart Van Assche, bart.vanassche@gmail.com)
