  other compiler internal function numbers (which are declared in innr.inc).

4ddbb7cd26 * Fixed assembler blocks to comply with x86_64 ABIs, which normally do not allow to change stack pointer at arbitrary locations. Register RBX is now saved/restored by compiler in function prologue, due to its presence in list of modified registers.

e4647ac133 - removed "nostackframe" from floating point helpers for llvm, as FPC 
doesn't handle nostackframe correctly in combination with extended

6909523b70 * handle atan, sqrt, ln, sin and cos in the x86 RTL for llvm 
o there are llvm intrinsics for all of these except for atan,
      but these obey "the same rules as the equivalent libc functions"
      and I first have to investigate whether these libc functions
      behave the same as our FPC implementations
