80282d6eff * llvm: only set custom parameter alignments for byval parameters, the rest 
is handled automatically by llvm (and since llvm 11.0 you get an error if
    you specify an alignment for them anyway)

9bd33f7a45 + support for LLVM metadata constant string parameters 
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)

1dee4c41dd - removed "cmp 0/1, pasbool1" optimization for llvm because this discards 
the upper 7 bits of the boolean, while other platforms take it into
    account (even though they're technically always required to be 0, and
    the value is undefined if they're not)

fceb34dbd5 * converted tllvmpara contents from tlocation to toper, so we can also 
store tai in them

    loading them into register)

4cd6f59bc3 * changed create_hlcodegen into a procvar, so that we don't have to insert 
hlcgllvm in the uses clause of every unit that calls create_hlcodegen
   o prevents dependency cycles that can cause llvm codegen units to init
     before the cpu variants, which is bad since the llvm versions have to
     override the cpu variants in their init code (+ added checks in the
     init code that they are in fact initialised later)

4686f61002 * keep track of the temp position separately from the offset in references,

04ac44cd37 - removed dependency of hlcgllvm on llvmpara, so that cpupara no longer 
indirectly depends on llvmpara and hence is initialised after instead
    of before it (since llvmpara should override cpupara in its init code)

a25ebbba3e + added volatility information to all memory references 
o separate information for reading and writing, because e.g. in a
     try-block, only the writes to local variables and parameters are
     volatile (they have to be committed immediately in case the next
     instruction causes an exception)
   o for now, only references to absolute memory addresses are marked
     as volatile
   o the volatily information is (should be) properly maintained throughout
     all code generators for all archictures with this patch
   o no optimizers or other compiler infrastructure uses the volatility
     information yet
   o this functionality is not (yet) exposed at the language level, it
     is only for internal code generator use right now
