6e8594a9af * patch by Nico Erfurth: Minor fix for FoldShiftProcess peephole optimizer on ARM

this is done in RegUsedAfterInstruction now.

5b02a7cb9b * patch by Nico Erfurth: Check for register reloading in RegUsedAfterInstruction on ARM 
This slightly changes the semantics of RegUsedAfterInstruction.
We now check if the `current value` of the register will be used later.
It will do `the right thing` for all the normal use cases.

2a2a1e5788 * patch by Nico Erfurth: Optimize SwapEndian for ARM 
The new version uses a pure pascal version for the 32bit case.
With the lastest compiler optimizations this generates optimal
4-instruction code which can be inlined. The rev-versions for
armv6+ are gone now, the inlineable pascal-code is faster than
the call-overhead for the rev-implementation.

The 64-bit versions received an updated assembly version which saves 4
cycles total on <armv6.

45c70ec81c * patch by Nico Erfurth: Support the usage of BIC instead of AND on ARM 
BIC clears the specified bits, while AND keeps them. The usage of BIC
allows a broader range of shifterconsts to be used on the ARM cpu, often
saving a cycle.

Previously code like:
Data:=Data and $FFFFFF00

would result in

mvn r1, #255
and r0, r0, r1

This patch changes this to

bic r0, r0, #255

fefc130efc * patch by Nico Erfurth: Handle BIC properly in taicpu.spilling_get_operation_type

83fb4c289d * patch by Nico Erfurth: Implement FoldShiftProcess Peephole optimizer for ARM 
This optimizer folds shift/roll operations into following data
instructions.

It will change code like:

mov r0, r0, lsl #16
add r1, r0, r1

into

add r1, r1, r0, lsl #16

Source registers will be reordered when necessary, also SUB/SBC will be
replaced with RSB/RSC and vice versa when reordering is required.

It could be expanded to support more operations like LDR/STR.

5393efb128 * patch by Nico Erfurth: Support A_MOV and A_MVN in RedundantMovProcess 
This changes the ARM Peephole optimizer RedundantMovProcess to also
recognize and modify something like the following sequence.

mov r0, r1
mov r0, r0, lsl #8

this would be changed into

mov r0, r1, lsl #8

4ea1d22c5a * patch by Nico Erfruth: Support BX for function returns on armv5+ 
BX is supported from ARMv4T onwards, but i don't have a armv4t device to
test it.

Using BX instead of mov pc,lr allows for a better pipeline utilization
by enabling the CPUs branch predictor to work properly.

9412d4abd2 * add a reference to the procsym corresponding to the chosen overloaded 
procdef, so that the unit containing it is marked as "used" (mantis #15966)

    Even better would be if the unit containing the originally found procsym
    were not also marked as used, but that would require a significant
    rewrite (all symbols found using symboltable helpers are automatically
    marked by those routines)

aa0f1bdf26 pdecl.pas, readconstant: If we are parsing a constant declaration in a generic and we encounter an intrinsic then this intrinsic is left as is (thus the node p returned by comp_expr will be a inlinen instead of an expected ordconstn, stringconstn, etc.). Nevertheless we need to create a symbol for the constant (which isn't done otherwise). In the case of SizeOf a constant "0" will be created. This fixes Mantis #21593.
