63602fb868 Do not CopyFromReg physregs for live-in values. Instead, create a vreg for
each live in, and copy the regs from the vregs.  As the very first thing we
do in the function, insert copies from the pregs to the vregs.  This fixes
problems where the token chain of CopyFromReg was not enough to allow reordering
of the copyfromreg nodes and other unchained nodes (e.g. div, which clobbers
eax on intel).

08b22ecc88 calling a function with the wrong CC is undefined, turn it into an unreachable
instruction.  This is useful for catching optimizers that don't preserve
calling conventions

fe07581d78 Make sure that decompression checks for the case that bzip2 returns
BZ_OK (meaning more data is expected) but there is no more input data. In
this case, the input file is probably truncated. Generate an exception that
indicates this case when its detected.

32b30a3c23 Fix this test on Solaris.
Solaris grep is more traditional and (AFAIK) does not support regexs.
Also, single quotes should disable all shell interpretation, so no
backslashes should be needed (and, in fact, keep Solaris from working).
