3ed60082d3 * don't generate typed constant initialisers for set and enum constants 
declared local to functions on the JVM target, because we don't generate
    field constants for them (fixes run time error when declaring a symbolic
    enum/set constant in a function on the JVM target)

66e82f1655 + i386: generate optimized code for 64-bit arithmetic shifts by constant amount. Shifts by 63 and by less than 32 take just two instructions, shifts by 32..62 bits are done with 3 instructions.

486a7ef81e * tx86inlinenode.second_popcnt: use emit_ref_reg instead of appending instruction directly, this provides proper PIC handling of the reference. emit_reg_reg part is not strictly necessary, but done for consistency.

6a08ca3f0b * tmoddivnode.firstoptimize improvements/fixes: 
* Fixed misplaced parentheses, which were preventing optimization of "unsigned mod power_of_two" into "and" expressions.
  * Handling "signed div power_of_two": properly delete the temp node, removes warnings when compiled with "-dEXTDEBUG". This however requires another temp node for storing the result.
  * Replaced direct calls to "fpc_sarint64" with inline nodes (in_sar_x_y), allowing target-specific optimizations to take place.

9ad98a2c4d * Handle "SarInt64" always as internal procedure, introduced virtual method tinlinenode.first_sar that by default converts it into call to "fpc_sarint64" unless target CPU is 64-bit. This provides a point to insert target-specific optimizations.

40239e8bcc * Elaborating removal of branches with delay slots: ignore reg. deallocations that are inserted by RA between branch and its delay slot instruction. 
* Also skip possible ait_marker's between branch and its immediately following target (which was preventing certain optimizations of "exit" statements on all targets because procedure's exit label is always preceded by location marker).
