If local spiller optimization turns some instruction into an identity copy, it will be removed. If the output register happens to be dead (and source is obviously killed), transfer the kill / dead information to last use / def in the same MBB.

Teach instcombine 4 new xforms:
...
(add (sext x), cst) --> (sext (add x, cst'))
(add (sext x), (sext y)) --> (sext (add int x, y))
(add double (sitofp x), fpcst) --> (sitofp (add int x, intcst))
(add double (sitofp x), (sitofp y)) --> (sitofp (add int x, y))
This generally reduces conversions. For example MiBench/telecomm-gsm
gets these simplifications:

This also fixes a bug in ComputeNumSignBits handling select and
makes it more aggressive with and/or.

convert fptosi(sitofp x) -> x if the fp value has enough bits in its mantissa

Fold FP comparisons where one operand is converted from an integer
...
type and the other operand is a constant into integer comparisons.
This happens surprisingly frequently (e.g. 10 times in 471.omnetpp),
which are things like this:
%tmp8283 = sitofp i32 %tmp82 to double
%tmp1013 = fcmp ult double %tmp8283, 0.0
Clearly comparing tmp82 against i32 0 is cheaper here.
this also triggers 8 times in gobmk, including this one:
%tmp375376 = sitofp i32 %tmp375 to double
%tmp377 = fcmp ogt double %tmp375376, 8.150000e+01
which is comparing an integer against 81.5 :).
