8001979f7e Reworked ispowerof2 in cutils.pas 
IsPowerOf2 now uses the BsfQWord intrinsic introduced in Freepascal 2.6,
instead of the old shl loop, to find the power.

71c13190e1 Fix for Mantis #22329. 
symtable.pas, searchsym_in_class:
* if we found a helper method that has overload defined we should not forget the symbol as there can be a case that no method with that name is defined in the extended class hierarchy
symtable.pas, searchsym_in_record:
* analogous to the above

+ added test given in the issue
+ added analogous test for record helpers

a908db5a91 Partially fix for Mantis #22160. This resolves the internal error, but the given example units still don't compile, because of the way we handle specializations and unit loading (more about this once I fixed that, too). 
pgenutil.pas, specialization_init:
* don't add implementation units of the generic's unit to the symtable stack if we are specializing in a different unit (thus the generic needs to be defined in the interface section) as there is the possibility that the globalsymtable of an implementation unit is not yet defined if the specialization unit is used in the interface section of an implementation unit

37b8cd1b7a * If relocation to a local label cannot be translated into (section+offset), then the target symbol must be written into symbol table. Fixes IE 200603012 in number of tests with -Cg on i386-linux (and possibly other targets with internal ELF assembler).

504a0ce0ca Fix for Mantis #22326 
This fixes 64bit shifts on arm with a constant shift value of 0.

The old code would have emitted something like this
mov r0, r0, lsl #32
as 32 is an invalid shift value (and would be wrong anyway) the
assembler declined to assemble the produced source.

The new code will just not emit any code for a shift value of 0.

tests/test/tint642.pp now tests shl/shr 0 on 64 bit values.
tests/webtbs/tw22326.pp is also added as an additional test.

65e701a198 * Fixed operation of 'PROVIDE' link script directive (all symbols were incorrectly put into .bss section, instead of locations given by placement of the directive). 
* Changed type of symbols created by link script from AT_FUNCTION to AT_DATA. This isn't significant for COFF, but matters for ELF targets.
* Changed alignment of .gnu_debuglink section from 0 to 1, this matches behavior of ld.

c65abdeeae * Implemented link map generation without involving TObjSection.ObjSymbolDefines, and removed the latter because it isn't used otherwise. The new approach uses CPU/memory only when map generation is requested.

b0462d27cc * by default, no longer initialize enumeration fields of classes/objects 
with the enum instance corresponding to ordinal 0 in JVM constructors,
    because a virtual method called by a parent constructor may already
    have assigned a different value (see tests/test/jvm/tenum2.pp). This
    will result in null pointer exceptions when using such fields without
    first explicitly assigning a value to them though.

    The old behaviour can be restored with the new -CTenumfieldinit command
    line parameter

bb28a7cd08 * decrease the fpu stack position counter after explicitly inserted 
fist(t)pq instructions (mantis #22331)
  * also internalerror in case the internal fpu stack position counter
    becomes larger than 7, so we don't have to wait for the entire
    byte to overflow before we detect a problem

1284be72ea * Fixed alignment of '.data' section, which got accidentally changed from 16 to 8 by r21374, causing e.g. tests/test/tasm3.pp to crash if compiled without -Cg and on target without tf_smartlink_sections. The root problem is not here, however: if appending data with higher alignment to a section with lower alignment, we likely need to raise the alignment of section.

0c32756ef3 - removed TCoffObjData.afteralloc, calculating MemPos there is useless because every call to afteralloc is immediately followed by call to TObjData.resetsections that resets all MemPos back to zero. 
- PE_FILE_RELOCS_STRIPPED flag is meaningless for object files.
- Don't write PE_FILE_BYTES_REVERSED_LO as well, it is deprecated and GNU tools don't write it either.
- Don't set PE_FILE_32_BIT_MACHINE flag in x86_64 object files.
