LCSSA is still the slowest pass when gccas'ing 252.eon, but now it only takes
39s instead of 289s. :)

is the same as the recent patch to LCSSA.cpp.

not handling PHI nodes correctly when determining if a value was live-out.

This patch reduces the number of detected live-out variables in the testcase
from 6565 to 485.

ComputeMaskedBits.  DemandedMasks and KnownZero/One masks should never have
bits set out of the range of the base datatype.

If a single exit block has multiple predecessors within the loop, it will
appear in the exit blocks list more than once.  LCSSA needs to take that into
account so that it doesn't double process that exit block.

Back out Owen's 6/9 changes. They broke MultiSource/Benchmarks/Prolangs-C/bison (and perhaps others).

nodes correctly.

as using incoming argument registers, so the local allocator would clobber them
between their set and use.  To fix this, we give the call instructions a variable
number of uses in the CALL MachineInstr itself, so live variables understands
the live ranges of these register arguments.

Use execve when explicit environment variables ptr is available. Otherwise
just use execv.

Change the file size field of StatusInfo to be uint64_t instead of size_t
so that we know it is always 64 bits. This prevents some overflow on
systems where size_t is 32 bits when it ought to be 64.
