25999ad8ff llvm: support for opaque pointers 
Will be the default starting with LLVM 15, and required with LLVM 16.
Tested with LLVM 14 and '-mllvm -opaque-pointers'. See
https://releases.llvm.org/14.0.0/docs/OpaquePointers.html for more
information.

a76085e463 tllvmcallpara: record whether it's passed to metadata

16cb409fbf LLVM: separate as_clang_llvm_darwin 
The Darwin local label prefix ('L') is different from that on most other
platforms ('.L). While LLVM generally handles that for us, for inline
assembly it's still FPC's job to adhere to the target conventions.

6e777d8967 * ait_comment,ait_regalloc,ait_tempalloc,ait_varloc instructions produce only comments in the external assembler output. Moved handling of these instructions to TExternalAssembler.WriteComments(). 
This eliminates code duplication and improves maintainability.

eb7ba1690e * mark all external assemblers using an LLVM tool using af_llvm 
+ added support for constructing target triplets
  * pass "-target triplet" when using an LLVM assembler
   o removed no longer needed $DARWINVERSION and $ARCH parameters
  * consistently use as_clang_gas when clang is used to assembler GAS-style
    assembly, and rename as_llcm_clang to as_clang_llvm (for consistency)
  * support pipe assembling when using clang on *nix in all cases

79974a9671 + -XlS<x> option to specify a suffix for externally called LLVM utilities, 
e.g. -XlS-7 to call clang-7 instead of clang)
  * IMPORTANT: changed the -CL llvm code generation options to -Cl, for
    consistency with the new -Xl option (-XL was already taken)

254b85c352 + new pio_inline_forbidden flag to indicate that while parsing the 
implementation the compiler determined the routine must never be
    inlined
   o difference with po_noinline: can also be set in the implementation
   o difference with pio_inline_not_possible: it indicates that e.g.
     LLVM must not inline the routine either

b355ba3d39 * record whether a function uses fastmath, and define the function as 
strictfp if it doesn't (so LLVM doesn't perform transformations that can
    change the fp/exception behaviour)

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)

c477816100 - removed LLVM support for clang < 7.0 and Xcode < 10.0: those versions 
contain various bugs and can't even complete "make all", so there is no
    point in keeping them
   o changed default LLVM target version to 7.0

d74b0843df * set null-pointer-is-valid attribute on functions, so that LLVM does not

    LLVM/Clang 7.0 or later)

fc60ec2ea4 + support for LLVM LTO: compile units with -CLflto -> when compiling a main 
program/library also with -Clflto, all units compiled with that option
    will be linked using their bitcode files and LTO
   o compiling with -CLflto will compile all units twice: once for normal
     (static or smart) linking, and once for LTO. So the result can be
     used both with and without LTO.

16cde0da15 * create LLVM TAsmCFI wrapper that calls through to the original TASmCFI for 
pure assembler routines and for generating the CFI tables, and does nothing
    for LLVM-handled routines (LLVM takes care of the CFI there)
