target-ppc: implement stxvl instruction
stxvl: Store VSX Vector with Length
Vector (8-bit elements) in BE:
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+--+--+
|“T”|“h”|“i”|“s”|“ ”|“i”|“s”|“ ”|“a”|“ ”|“T”|“E”|“S”|“T”|00|00|
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+--+--+
Vector (8-bit elements) in LE:
+--+--+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
|00|00|“T”|“S”|“E”|“T”|“ ”|“a”|“ ”|“s”|“i”|“ ”|“s”|“i”|"h"|"T"|
+--+--+---+---+---+---+---+---+---+---+---+---+---+---+---+---+
Storing 14 bytes would result in following Little/Big-endian Storage:
+---+---+---+---+---+---+---+---+---+---+---+---+---+---+--+--+
|“T”|“h”|“i”|“s”|“ ”|“i”|“s”|“ ”|“a”|“ ”|“T”|“E”|“S”|“T”|FF|FF|
