58604cd944 Change default error_code ctor to a 'named ctor' so it's more self-documenting.
Unify default construction of error_code uses on this idiom so that users don't
feel compelled to make static globals for naming convenience. (unfortunately I
couldn't make the original ctor private as some APIs don't return their result,
instead using an out parameter (that makes sense to default construct) - which
is a bit of a pity. I did, however, find/fix some cases of unnecessary default
construction of error_code before I hit the unfixable cases)

4aab4ab340 Remove SetWorkingDirectory from the Process interface. Nothing in LLVM
or Clang is using this, and it would be hard to use it correctly given
the thread hostility of the function. Also, it never checked the return
which is rather dangerous with chdir. If someone was in fact using this,
please let me know, as well as what the usecase actually is so that
I can add it back and make it more correct and secure to use. (That
said, it's never going to be "safe" per-se, but we could at least
document the risks...)

8a86887ba3 use getHostTriple instead of getDefaultTargetTriple in getClosestTargetForJIT
Get back getHostTriple.

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

aabc6a9b79 Remove the hack to check UNAME_RELEASE when identifying the Darwin version.
This was only needed to locate llvm-gcc's installation directory when clang
falls back to run llvm-gcc for i386 kexts.  As of clang svn r140187, we're
now just searching paths with several different Darwin versions on either
side of the current version, so this is no longer needed.

3c036e520e Teach Path::GetCurrentDirectory to use $PWD, to support users who like to do
screwy things by setting PWD != getcwd(). For example, some developers I know
will use this to control the value in gcc's DW_AT_comp_dir value in debug
output. With this patch, that trick will now work on clang too.

The only other effect of this change is that the static analysis will now
respect $PWD when reporting the directory of the files in its HTML output. I
think that's fine.

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.
