176d8434e4 * SPARC: completely rewrote PIC-related code, got it twice shorter in source lines and much less instructions in generated code. 
+ Enable registers %i0..%i5 and %o7 for use by reg.allocator.

Some notable properties of this implementation are:
  o pi_needs_got flag can be safely set during pass 2, so not setting it occasionally in pass 1 does not result in internal error.
  o Reg.allocator configuration is independent from PIC. If procedure requires GOT, register %l7 is allocated at the prologue, making it unavailable to RA.
  o GOT is stored in fixed %l7 register, but it is trivial to switch over to virtual register.

1a3b46967e + Two more checks for access to global data and setting the pi_needs_got flag, intended for targets that require decision about PIC code generation strictly before pass 2.

eaba90dda7 * SPARC: since peephole optimizer recognizes only one conditional branching instruction, generate all branches using A_Bxx opcode, and change it to A_FBxx if necessary when writing assembler. This enables optimization of floating-point branches. 
* Assembler reader: rewrote branch condition matching part, don't try to match integer suffixes to floating-point branches and vice versa.

03fb83cc01 * SPARC: fixed PIC interface wrappers for non-virtual methods. The fix uses branching with 8 MB distance limit, but in particular case of interface wrappers this limit applies to code size of a single unit, not to entire program, and is therefore hard enough to reach.

af49e50a3c * do not cause an internal error when location_reg2string is called on a 
location where the registers have been translated (i.e. not imaginary), but
  GetNextReg is necessary to get some of the registers (only on 16/8-bit CPUs).
  The missing registers are indicated as '??'. This avoids a crash when
  compiling a system unit on i8086 with regvars enabled and withous -sr, while
  still giving the full list of registers when compiling with -sr.
