a8bc2085e8 - Delete strpas.inc files, no longer used, their contents has been merged into corresponding $(CPU).inc.

fc5f45f65c * sqr(real) and sqrt(real): remove typeconv node inserted by initial call processing (see explanation in comments), allowing these functions to be evaluated using precision of argument. In particular, sqrt(single) and sqrt(double) now emit 'sqrtss' and 'sqrtsd' instructions on x86 targets with -Cfsse3. Non-x86 targets already have the necessary support in code generators. 
* abs(real): handle the same way as sqrt and sqr, i.e. without casting to bestreal and back.

b16c6f8ced * i386 and x86_64 changes for Delphi compatibility: 
* 'mxcsr' variable made public and renamed to DefaultMXCSR.
  * GetSSECSR and SetSSECSR renamed to GetMXCSR and SetMXCSR, respectively. Previous names continue to exist as deprecated aliases.

6baba5065c * i386: Perform all CPU-related initialization in fpc_cpucodeinit, instead of having it scattered between fpc_cpuinit,fpc_cpucodeinit and check_sse_support. Simplifies things quite a bit.

74f9d719f1 * i386-win32 setjmp and longjmp: if SEH support is enabled, save/restore head of exception registration chain. Without this, a longjmp out of a function with exception frame(s) will leave these exception frames below ESP, which will fail integrity checks in OS and cause process termination if an exception occurs later on (or they may be overwritten by subsequent operations on stack and, again, cause undesired results). 
* Additionally, use a branchless sequence to fix up result of longjmp.

8469741700 + Added additional addr pointer parameter to 
get_caller_frame, get_caller_addr and dump_stack
  with default NIL value to systemh.inc.
  + Added new get_addr function.
  system.inc: Use get_addr and get_frame to call
  HandleErrorAddrFrame instead of HandleErrorFrame
  in several error functions.
  Modify dump_stack to use frame and addr parameters.
  Provide a dummy get_addr function returning nil.
  i386/i386.inc, x86_64./x86_64.inc: Provide real
  implementation of get_addr function.

06192a8137 Values of managed variables are never ever used after decrementing reference on the variable, so there is no point of having a 'decrement reference' as a separate operation. We can always do 'finalize', i.e. clear the contents after decref. 
* Modified fpc_ansistr_decr_ref and fpc_widestr_decr_ref so they always zero the pointer passed by reference. Other _decr_ref helpers already do it.
- Removed tcg.g_decrrefcount, calling cg.g_finalize instead.
- finalize_data_node and tcg.g_finalize: removed code generation for zeroing locations, because it is now done by RTL helpers. This further reduces code size.

As a total result of this change and r20118, the size of Lazarus executable is reduced by about 12%.

009ee271ec - Cleaned out STR_CONCAT_PROCS define 
- i386-specific fpc_shortstr_append_shortstr removed too, because a) it was anyway disabled with STR_CONCAT_PROCS, b) the generic implementation is smaller and probably faster due to optimized Move().
