This adds rules to match the code in math/bits RotateLeft,
RotateLeft32, and RotateLef64 to allow them to be inlined.
The rules are complicated because the code in these function
use different types, and the non-const version of these
shifts generate Mask and Carry instructions that become
subexpressions during the match process.
Also adds a testcase to asm_test.go.
Improvement in math/bits:
BenchmarkRotateLeft-16 1.57 1.32 -15.92%
BenchmarkRotateLeft32-16 1.60 1.37 -14.37%
BenchmarkRotateLeft64-16 1.57 1.32 -15.92%

The optimised P-256 includes a CombinedMult function, which doesn't do
dual-scalar multiplication, but does avoid an affine conversion for
ECDSA verification.
However, it currently uses an assembly point addition function that
doesn't handle exceptional cases.

On ppc64le, functions compiled with -shared expect r12 to
hold the function's address for indirect calls. Previously
this was enforced by generating a move instruction if the
address wasn't already in r12. This change avoids that extra
move by requesting r12 in the CALL ops that do indirect calls.
As a result of adding support for plugins on ppc64le, it was
discovered that there would be more cases where this extra
move was needed, so this seemed like a better solution.

go build -buildmode=plugin -o=p2.so main.go
