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)

* disable matching volatile references in the assembler optimisers, so they
can't be removed (more conservative than needed, but better than removing
too many)
o the CSE optimiser will ignore them by default, because they're an unknown
inline node for it
* also removed no longer used fpc_in_move_x and fpc_in_fillchar_x inline node
identifiers from rtl/inc/innr.inc, and placed fpc_in_unaligned_x at the
right place

o use this to handle non-power-of-two-sized parameters for llvm
o no general support in the parser/code generator, so don't expose
git-svn-id: trunk@40398 -
* compinnr.inc include file converted to a unit
* inline number field size stored in ppu increased from byte to longint
* inlines in the parse tree (when written with the -vp option) now printed with
their enum name, instead of number

Since overloading compilerprocs does not work each procedure got its own unique name, but they are using the new compilerproc extension to map them to the Insert and Delete symbol so that error messages can be shown with the respective name for the procedure declarations instead of fpc_shortstr_delete for example.

pasbool8type for this results in too much trouble (we mustn't use i1
for parameters, because then LLVM will try to apply the ABI convention
for passing "1 bit" values, or in records because then this may
result in unwanted bitpacking). Downside: the new LLVMBool1 type is
also exposed in the system unit, because we need it to define LLVM
intrinsics...

The result type of the intrinsic is determined by the Then-expression to provide a bit of control. There might however be some situations in which this fails, for this exceptions need to be added (e.g. a constant string needs to be converted to a normal string).
compinnr.inc:
+ add new constant in_ifthen_x_y_z for the IfThen() intrinsic
psystem.pas:
+ create_intern_symbols: add symbol for IfThen() intrinsic
pexpr.pas:
* statement_syssym: parse parameters of IfThen() intrinsic and return corresponding inline node
ninl.pas, tinlinenode:
+ new method handle_ifthen() which converts the inline node to an if-node which assigns the expressions to a temp node that is returned
* pass_typecheck: handle in_ifthen_x_y_z using handle_ifthen()
* pass_1: in_ifthen_x_y_z does not need a first pass as it's already converted after the typecheck pass
+ added tests

* for now all undefineddefs are created as registered
Note: an additional parameter instead of an overload is used for tundefineddef.create as otherwise both constructors would need to be overridden in potential descendant CPU-specific classes...
