(fixes most of test/units/math/troundm, although there's still an LLVM
optimizer/code generation bug that breaks some qword -> double
conversions)

o they are implemented as a new metadata register class, whereby the
subregister indicates the metadata type (currently always a string)
and the superregister is an index in the metadata array (which
contains the strings). LLVM metadata can only be passed as parameters
to intrinsics in bitcode, so moves of metadata into other registers
triggers internal errors and when moving them into parameters, we
replace the parameter's register with the metadata register (and look
up the corresponding string when writing out the bitcode)
