ea6250898a New function mps_root_create_reg_masked applies a mask and pattern test to all words in registers and on the stack when scanning them. this supports tagged references in these locations. 
Consistently use the type "Word *" for pointers into the stack or into saved registers.
Remove TraceScanAreaTagged.

testrun.sh now takes a "runner" via the -r option. You can pass something like "noaslr" to run all the test cases with ASLR turned off.

31795d3b7b In mpmcheck, assert that stackprobedepth words will fit into a page, so that we find out if design.mps.sp.sol.depth.constraint is ever violated. 
Format methods must have bounded stack usage for stack probing to be effective, so document this in the manual (picking the arbitrary value 64 for the bound, which should be more than enough).
