d512ed689c 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.)

b727c53cff Revert r77396. 
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).

5eeaebe9b8 Remove try/catch(...) from Win32/Signals.inc. 
catch(...) is used in Win32/Signals.inc for catching Win32 structured
exceptions, but according to [1], this is wrong.

We can't simply change try/catch to __try/__finally, since this syntax is not
supported by MinGW. We can use __try/__finally on MSVC and __try1/__except1
macros on MinGW [2], but I think that that solution obfuscates the code too
much.

The use of try/catch(...) in Signals.inc makes it impossible to link
MinGW-compiled libSystem with llvm-gcc compiled executables. I propose that we
just remove try/catch(...) from Signals.inc, since the meaning of the code won't
change.

8119017726 ATTRIBUTE_UNUSED has been renamed to LLVM_ATTRIBUTE_UNUSED. 
Rather than rename this instance, use the cast-to-void idiom
instead.  This will hopefully fix the windows buildbots.

3bca7bf84d System: Fix getMagicNumber on windows. 
getMagicNumber was treating the _binary_ data it read in as a
null terminated string. This resulted in the std::string
calculating the length, and causing an assert in other code that
assumed that the length it passed was the same as the length of
the string it would get back.

5cb73a9fb8 Don't cast Win32 FILETIME structs to int64. Patch by Dimitry Andric! 
According to the Microsoft documentation here:
http://msdn.microsoft.com/en-us/library/ms724284%28VS.85%29.aspx

this cast used in lib/System/Win32/Path.inc:

__int64 ft = *reinterpret_cast<__int64*>(&fi.ftLastWriteTime);

should not be done.  The documentation says: "Do not cast a pointer to a
FILETIME structure to either a ULARGE_INTEGER* or __int64* value because
it can cause alignment faults on 64-bit Windows."

093ad188e7 CrashRecovery/Darwin: On Darwin, raise sends a signal to the main thread instead 
of the current thread. This has the unfortunate effect that assert() and abort()
will end up bypassing our crash recovery attempts. We work around this for
anything in the same linkage unit by just defining our own versions of the
assert handler and abort.
