ppc64spec command

Power64spec reads the “Power ISA V2.07” Manual to collect instruction encoding details and writes those details to standard output in CSV format.

Usage:

ppc64spec PowerISA_V2.07_PUBLIC.pdf >ppc64.csv

Each CSV line contains four fields:

instruction
	The instruction heading, such as "AAD imm8".
mnemonic
	The instruction mnemonics, separated by | symbols.
encoding
	The instruction encoding, a sequence of name@startbit| describing each bit field in turn.
tags
	For now, empty.

For more on the exact meaning of these fields, see the Power manual.
