Benjamin Kramer b49b964b98 InstCombine: Turn umul_with_overflow into mul nuw if we can prove that it cannot overflow. 
This happens a lot in clang-compiled C++ code because it adds overflow checks to operator new[]:
  unsigned *foo(unsigned n) { return new unsigned[n]; }
We can optimize away the overflow check on 64 bit targets because (uint64_t)n*4 cannot overflow.

Howard Hinnant 8cad46266c I have to revert this recent fix to tuple conversions until clang implements cwg 1170. Without this fix pair and tuple don't convert properly. With it, associative containers get access errors when they shouldn't. cwg 1170 fixes the latter.

Ted Kremenek a099c595bf When doing reachability analysis for warnings issued under DiagRuntimeBehavior, don't construct a ParentMap or CFGStmtMap. 
Instead, create a small set of Stmt* -> CFGBlock* mappings during CFG construction for only the statements we care about
relating to the diagnostics we want to check for reachability.

Stephen Wilson 1636265248 Add Makefile support for the Platform plugins. 
This patch supports building the Linux platform plugin, and should also support
the MacOSX plugin as well (the MacOSX side has not been tested, unfortunately).
A small typo was corrected in lldb.cpp to initialize the new platform code on
Linux.

Greg Clayton c574ede632 Centralize the GDB remote timeout value into the GDBRemoteCommunication as a 
member variable (m_packet_timeout which is a value in seconds). This value is
then used for all packets sent to/from the remote GDB server.

Ted Kremenek f9d8290af1 Rework interaction between AnalysisContext and CFG::BuildOptions to keep a BuildOptions object around instead of keeping a copy of the flags. 
Moreover, change AnalysisContext to use an OwningPtr for created analysis objects instead
of directly managing them.

Finally, add a 'forcedBlkExprs' entry to CFG::BuildOptions that will be used by the
CFGBuilder to force specific expressions to be block-level expressions.

Evan Cheng ca9a936332 Change the definition of TargetRegisterInfo::getCrossCopyRegClass to be more 
flexible.

If it returns a register class that's different from the input, then that's the
register class used for cross-register class copies.
If it returns a register class that's the same as the input, then no cross-
register class copies are needed (normal copies would do).
If it returns null, then it's not at all possible to copy registers of the
specified register class.

Johnny Chen 9363d41f14 LLVM combines the offset mode of A8.6.199 A1 & A2 into STRBT. 
The insufficient encoding information of the combined instruction confuses the decoder wrt
UQADD16.  Add extra logic to recover from that.
