+ add a comment to the destructor of tsymtable so that others (and maybe me a well) will hopefully see that the destructor of that class is not completely trivial!

* fixed some issues to get correct values of section_count, works better than before but it is still not perfect for unknown reasons

* forgotten part of 0039750

+ based on a patch by Laksen, optimize (v>=x) and (v<=y) into (v-x)<(y-x)

* support aitconst_*bit_unaligned in the intel assembler writer, resolves 0034222

* relax formula for max. nodes to inline

cleanup: remove ARMHF-related comments from RISC-V only codepath. no functional change.

* addendum for Mantis 0034333: also complain about number of arguments with the maximum number of arguments for Copy ( = 3 ) is exceeded

* is_range_test returns false if "lower" bound is greater than "upper" bound

* fix building with LLVM=1, thanks to Karl-Michael Schindler for the hint

+ patch by J. Gareth Moreton to support BMI2 instructions
+ extended avx test generator with the newly added BMI2 instructions

* Fixed overflow error when calling align() with corner case values such as align($7FFFFFFC, 4) for the longint variant.

Fix riscv64 compiler compilation with -dEXTDEBUG

Fix compilation with -dEXTDEBUG

Add -Tlinux and -Tembedded help lines for riscv32 and riscv64 compilers

* Fixed writing of method's RTTI for aarch64 by explicitly writing the $self parameter first.

* Reverted 0039947. According to Sven, the $self parameters is not required to be first parameter in RTTI. Appropriate tests will be fixed.

* Fixed overflow error for the qword version of align() when i=0.

* Undef FPC_HAS_TYPE_EXTENDED for x86_64-android.

* Reverted 0039961.

* avoid range check errors

* remove .NOTPARALLEL: from compiler Makefile, accelerates make fullcycle with -j a lot
* few cleanups

* typo

* fullinstall builds (and installs) utils now only once

* use the built compiler to install files, so the version is set correctly

* make install shall not make assumptions about FPC, if one was provided

+ make use of the BFI instruction in tcgaarch64.a_load_ref_reg_unaligned

* cleanup debug code

+ implement assembler optimization Str/LdrAdd/Sub2Str/Ldr Postindex done

* avoid to create a stack frame on aarch64 if possible

* take care of the fact that x and w registers overlap when carrying out the Str/LdrAdd/Sub2Str/Ldr Postindex optimization

* Optimized generic implementations of tcg.a_op_const_ref() and tcg.a_op_reg_ref() for PIC and CPUs which need 2 or more instructions to load a symbol's value by reference.
First the symbol's address is taken and then it is used to load the value and also store the result. It eliminates extra calculation of the symbol's address needed to store the result.
x86 and other CPUs which can handle refs ops directly or more efficiently already have overloaded versions of these methods and are not affected by this change.

* SetExecutionWeight(): Set execution weight also for nodes with special handling. Minor code cleanup/improvements.
* Restore previous execution weight before exiting secondpass().
* It all improves register allocation for variables inside loops in some cases.

* version update

* replaced "is" test with faster field value test

- x86 align does not use a register anymore, code removed

+ introduce tai_align_abstract.create_max which limits the maximal number of bytes being inserted for alignment

+ new fields for more precise control of alignment
+ support of new alignment control values for GNU AS writer
+ support of new alignment control values for binary writer
* better alignment settings on i386-win32
* improved inserted align directives for if nodes
