This change allows bugpoint to pinpoint the "opt" pass and bitcode
segment responsible for a crash caused by miscompilation. At least it
works well for me now, without having to create any custom execution
wrappers.

I've been using this mode to narrow down llc unit tests. Example
custom compile script:
llc "$@"
not pygrep.py 'mul\s+r([0-9]), r\1,' < bugpoint-test-program.s

PATH isn't actually searched, and to not mention the executable
directory when it isn't actually searched.

bugpoint does "Running the code generator to test for a crash" this
gets you a crash if llc goes into an infinite loop or uses up vast
amounts of memory.

The revision history for this function is interesting, with multiple layers of
wrongness being introduced one at a time.
This fixes a weird issue where bugpoint -run-llc would suddenly exit 13 half way
through isolating a miscompilation.

works for me: bugpoint Output/bisort.llvm.bc -run-llc-ia -safe-run-llc
This uses llc with the integrated assembler as the test compiler and llc
without it as the safe compiler.

This is conventional command-line tool behavior. -f now just means
"enable binary output on terminals".
Add a -f option to llvm-extract and llvm-link, for consistency.
Remove F_Force from raw_fd_ostream and enable overwriting and
truncating by default. Introduce an F_Excl flag to permit users to
enable a failure when the file already exists. This flag is
currently unused.
Update Makefiles and documentation accordingly.

member out of line. ftostr is not particularly speedy,
so that method is presumably not perf sensitive.

forcing them down into various .cpp files.
This change also:
1. Renames TimeValue::toString() and Path::toString() to ::str()
for similarity with the STL.
2. Removes all stream insertion support for sys::Path, forcing
clients to call .str().
3. Removes a use of Config/alloca.h from bugpoint, using smallvector
instead.
4. Weans llvm-db off <iostream>
sys::Path really needs to be gutted, but I don't have the desire to
do it at this point.

- This is cleaner, and makes bugpoint match the host instead of the build
architecture.

just argv[0]. And remove the code for searching the current
working directory and for searching PATH; the point of FindExecutable
is not to find whatever version of the executable can be found by
searching around, but to find an executable that accompanies the
current executable.
Update the tools to use sys::Program::FindProgramByName when they
want PATH searching.

an existing file is considered an error. Convert several tools
to use raw_fd_ostream instead of std::ostream, and to use this
new option instead of doing a manual check.
