test/Scripts/macho-dump: Make hack for Python-2.4. [PR7995]
...
With Python-2.4, Reader::read64 always returns (unexpected) long integer.
FileCheck detects failure on test/MC/MachO among '0' and '0L'.
CentOS5(aka RHEL5 clone) provides python-2.4.

Replace SplitKit SSA update with an iterative algorithm very similar to the one
...
in SSAUpdaterImpl.h
Verifying live intervals revealed that the old method was completely wrong, and
we need an iterative approach to calculating PHI placemant. Fortunately, we have
MachineDominators available, so we don't have to compute that over and over
like SSAUpdaterImpl.h must.
Live-out values are cached between calls to mapValue() and computed in a greedy
way, so most calls will be working with very small block sets.
Thanks to Bob for explaining how this should work.

Revert r117582, which reverted r77396. Searching PATH for a string
...
which contains slashes is inconsistent with the meaning of PATH on
Unix-type platforms, and pretty surprising.
If the user has given a specific path to execute and we can't
execute it, we should fail and say why. (Apparently the new
posix_spawn code doesn't always say why, but that's a separate
issue.)

Original commit message:
On "Unix", if Program::FindProgramByName is given a name containing
slashes, just go with it, regardless of whether it looks like it will
be executable. This follows the behavior of sh(1) more closely.
It's better when behaviour is consistent between platforms. This change also
makes FindExecutable() behave as expected on unix-likes (before this commit, it
used to always succeed).
