Remove exception throwing from Path::getDirectoryContents and its users.

llvm-svn: 29841

Remove exceptions from the Path::create*OnDisk methods. Update their users
to handle error messages via arguments and result codes.

triplet ordering (large, small, small) explicit with one triplet per line.

Adjust code to compensate for Path class interface change.

llvm-svn: 29837

Change the Path::make*OnDisk methods exception free and adjust their usage.

memory pressure. This order spaces out large executables with small ones in
between so that in a -j2 or -j3 build, it only attempts to build only one
large executable at time. If you're doing -j4, you probably have enuogh
memory anyway.

Also corrected a problem where if the build failed the nightly tester
would still try to read the results of the Dejagnutests log even
though it didnt exist.

Adjust the use of MappedFile to its new non-throwing interface. We just
propagate the exceptions if an error occurs. This will get cleaned up
later, incrementally.

llvm-svn: 29820

Make the Bytecode Reader use setjmp/longjump instead of exceptions to handle
errors. The alternative was even uglier than setjmp/longjump as it would
impact the interface and workings of nearly every function in the reader.

llvm-svn: 29819

Adjust to new interface for MappedFile. Note that the new "throw"
statements will be removed later.

llvm-svn: 29818

Adjust users of MappedFile to its new non-throwing interface.  Note that in
most cases the lazy step of just throwing after a call to MappedFile was
installed. This was done in the name of incremental changes. Getting rid of
the new throw statements will take adjustment of interfaces and propagation
of errors to higher levels.  Those changes will come in subsequent patches.

llvm-svn: 29817

Make MappedFile not throw any exceptions.

Fix a bug in my last patch that botched file redirection by using explicit
scoping of if statements.
