98c9716c34 Eliminate zext over (iv & const) or ((iv+const)&const) 
if a longer iv is available.  These subscript forms are
not common; they're a bottleneck in OpenSSL.

5555c4538b Generalize one of the SelectionDAG::ReplaceAllUsesWith overloads 
to support replacing a node with another that has a superset of
the result types. Use this instead of calling
ReplaceAllUsesOfValueWith for each value.

427e9aade9 Enhance induction variable code to remove the 
sext around sext(shorter IV + constant), using a
longer IV instead, when it can figure out the
add can't overflow.  This comes up a lot in
subscripting; mainly affects 64 bit.

a1fe2a3741 Add a new MOV8rr_NOREX, and make X86's copyRegToReg use it when 
either the source or destination is a physical h register.

dba98a0669 Optimize conditional branch on i1 phis with non-constant inputs. 
This turns:

eq:
        %3 = icmp eq i32 %1, %2
        br label %join

ne:
        %4 = icmp ne i32 %1, %2
        br label %join

join:
        %5 = phi i1 [%3, %eq], [%4, %ne]
        br i1 %5, label %yes, label %no

=>

eq:
        %3 = icmp eq i32 %1, %2
        br i1 %3, label %yes, label %no

ne:
        %4 = icmp ne i32 %1, %2

3c19cf07d9 When the result of an EXTRACT_SUBREG, INSERT_SUBREG, or SUBREG_TO_REG 
operator is used by a CopyToReg to export the value to a different
block, don't reuse the CopyToReg's register for the subreg operation
result if the register isn't precisely the right class for the
subreg operation.

Also, rename the h-registers.ll test, now that there are more
than one.

df9499583d Call CreateProcess with bInheritHandles = TRUE. 
Makes llvmc show error messages printed by child processes when run from the
Cygwin/MSYS shell. Since ExecuteAndWait does not return until the child program
has finished execution, this change should be harmless.

9f44d3148c Fix PR3934 part 2. findOnlyInterestingUse() was not setting IsCopy and IsDstPhys which are returned by value and used by callee. This happened to work on the earlier test cases because of a logic error in the caller side.
