Optimize ARM OP_MUL/OP_IMUL for x*ispowerof2(const+1) cases
Calculations like a*7 can be optimized to a*8-a with the usage of RSB and left
shifts which can be done in a single cycle.

rather than with single/double quotes depending on the target platform
(ld only supports double quotes), and rather than only quoting when
necessary (wastes time since quotes are always allowed, and double
quotes inside a directory name cannot be escaped for ld; they are
simply not supported by the program) (mantis #22059, follow-up to
r21069 and r21208)

target the AIX linker
* never quote file names added to link.res when it's not a linkerscript
(only newline is a separator in the case)

+ implement trashing of local variables if subroutine is inlined
* fix some errors releated to interproc. gotos and inlining
+ node_count function
* inline cannot be used with iochecking and safecall calling conventions
* track inherited usage
* don't inline if inherited is used

method's visibility, because this is common practice in Object-Pascal.
It can be re-enabled with {$warn INTF_RAISE_VISIBILITY on} (mainly
useful when trying to keep code compatible with the JVM target)

constants on Darwin, because its linker uses global symbols as delimiters
of subsections for dead code stripping. This was previously solved by
never making any ansistring constants smart linkable, which is now
solved
git-svn-id: trunk@21328 -
* added some new minor deprecations (mostly unused constants that are
potentially not crossplatform, and an shortstring version of a function)
git-svn-id: trunk@21321 -
* modified fpmake files in packages to allow a "make all" for NativeNT in packages to work (nearly all packages need to be disabled; the main cause for this are the still missing DOS and Objects units for the target)

Improve ARM-Peephole Optimizers
1.) Introduce a ARM-specific RegUsedAfterInstruction which analyzes
instructions and reg allocation information to see if a register is
really needed afterwards to decide if some special optimizations can be
done.
2.) Introduce "RemoveSuperfluousMove"
This tries to fold mov into a previous Data-Instruction (ADD, ORR, etc)
or LDR-Instruction.
3.) Introduce new Optimizer "DataMov2Data" and modify LdrMov2Ldr to use
RemoveSuperfluousMove
4.) Expand Ldr* and Str* Optimizers to also work on {Ldr,Str}{,b,h}

Inline a couple of small functions of the ARM-Compiler
These small changes improved overall compile times of the fpc suite by
about 2-3% running on an 1.2GHz Kirkwood.
