Performance improvements to make struct-arrays benchmark faster
...
- improved optimization of ##unbox-any-c-ptr on ##box-displaced-alien; convert it to ##unbox-c-ptr where possible using class info stored in the ##bda instruction
- make fcos, fsin, etc inline again; everything in math.libm inline again, except for fsqrt which is an intrinsic
- convert min and max on floats to float-min and float-max
- make min and max not inline, so that the above can work
- struct-arrays: rice a bit so that more fixnums come up

compiler.tree.propagation: bitand custom inlining was wrong if the second input was a bignum

Delete empty unit tests files, remove 1- and 1+, reorder IN: lines in a lot of places, minor refactoring

Improve code generation for shift word: add intrinsics for fixnum-shift-fast in the case where the shift count is not constant, transform 1 swap shift into a more overflow check with open-coded fast case, transform bitand into fixnum-bitand in more cases

define-partial-eval framework in propagation pass makes it easy to add transforms; moving some transforms from stack checker to propagation, making them stronger
