	cm3/m3-sys/m3middle/src/: Target.i3 Target.m3 

Log message:
	add SPARC32_SOLARIS
	
	correct jmpbuf sizes for I386_SOLARIS, AMD64_SOLARIS
	notice again that jmpbuf is much much smaller than sigjmpbuf,
	and this is jmpbuf; specifically:
	I386_SOLARIS jmpbuf 40 bytes with 4 align
	AMD64_SOLARIS jmpbuf 64 bytes with 8 align
	I386_SOLARIS sigjmpbuf 512 bytes with 4 align
	AMD64_SOLARIS sigjmpbuf 1024 bytes with 8 align
	
	remove some level of heap allocation of calling conventions
	
	accept all calling conventions for all targets
	Only NT386 has calling conventions, and it *highly* likely
	the only target ever to have them, therefore the mechanism
	does not need to be further generalized. (MIPS32 has two
	ABIs, but those will probably be two targets)
	This might let us save some unnecessary forking of *.i3 files.
	The initialization here can be further streamlined.
	
	shrink SOLgnu/SOLsun from sigjmpbuf to jmpbuf
	I'm not sure we use this though since we have a stack walker.
	fix SPARC64_SOLARIS too to be smaller

	alignment: 4 4
	
	SPARC64_SOLARIS
