8382c6f586 Added generic WCH32Vx RISC-V processor types using memory size suffixes 
Modified low-level startup code for RISCV32 embedded microcontrollers to
allow user code override of reset handlers for non-power-up reset events
as well as enabling user code override handlers for all 255 possible
interrupt vectors.
Separated out the low-level startup memory init into a callable procedure
to allow users that have caught reset events to init memory again if needed.

87e4931489 Fix fullcycle compilation error due to -Sew option 
Add 'else' branch to 'case' keyword construct
  for the setting of ABI in riscv32 assembler call.
  Do the same for riscv64 assembler call.

f5cf8956c5 riscv: Merge stack code, fix interrupted code 
- Stack pointer is kept below register save area. This ensures that
registers are not overwritten by interrupt handlers.
- RV32 and 64 code is merged to base class.

3fee990218 * on Mach-O, PECOFF and ELF platforms, write local symbols as hidden/ 
private_extern (or plain global in case of PECOFF, as the effect is
    the same there): visible across object files, but they become local
    when linked into a binary/library. This enables cross-unit inlining
    of functions accessig implementation-only symbols.
