Cwd::abs_path has a somewhat tricky semantics: if it's operand directory does not exist,
it'll return undefined (see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=257568).
This may cause scan-build to silently ignore output directory (specified with -o) and
use /tmp instead of trying to create directory. This tiny patch fixes the problem.

In addition to r251524: preserve the order the checkers were enabled/disabled to be deterministic.
Additionally return the number of arguments read by 'ProcessArgs' - for debug purpose.
llvm-svn: 251552
A checker may be enabled/disabled multiple times via -enable-checker and -disable-checker scan-build arguments. Currently the conflicting and repetitive arguments are passed to the analyzer as is.
With this patch only the last enable/disable of a particular checker is accepted and passed to the analyzer.
This change is mostly done for the upcoming 'config for scan-build' patch when multiple inclusions/exclusions of a checker are expected to be more common.

The regex for -isystem matching is broken. -[D,I,Usystem] matches "-D", "-,",
"-I", "-U", "-s" "-y", etc. Besides that, "-isystem /foo" gets interpreted as
"-i" with a non-empty value "system" and thus the next "/foo" argument is not
read. This patch corrects the regex.
This fixes PR13237 <https://llvm.org/bugs/show_bug.cgi?id=13237>.

Update ccc-analyzer to forward both -Xclang and its following argument to the
the compiler driver. Previously we were dropping -Xclang and forwarding the
argument on its own if it matched other forwarding criteria. This caused the
argument to be interpreted as a driver rather than a frontend option.

- scan-build help: display 'Could not query Clang for the list of available checkers.' + the reason why it happened so if clang was not found.
- display requested/forced help in case of --use-analyzer=Xcode.
llvm-svn: 247828
- Eliminate 'No such file or directory at scan-build line ...' error if '$RealBin/bin/clang' or '$RealBin/clang' directory does not exist.
- Eliminate 'Use of uninitialized value $Clang in concatenation (.) or string at scan-build line ...' error if help is displayed while $Clang was not found.

Full list of changes:
- all scan-build command-line arguments are now kept in %Options hash.
- most of environment variables scan-build operates with are stored in %EnvVars hash.
- moved processing of command-line arguments to the ProcessArgs subroutine.

When interposing on a compiler doing cross-compilation, scan-build
does not infer the target triple needed to pass to clang for
doing static analysis. The --analyzer-target option allows one
to manually specify the target triple used during static analysis
(and only static analysis) for such cases.

'fork'+'exec' combination made scan-build and ccc-analyzer hang under Windows. The patch replaces 'fork'+'exec' with more reliable 'system' (ccc-analyzer) and piped 'open' (scan-build). See http://reviews.llvm.org/D8774 and http://reviews.llvm.org/D9357 for more details.

An old code caused problems under Windows - additional temporary file was created for clang preprocessor output while the right output file remained empty.

Summary:
This patch removes useless whitespace in File path in index.html
Previously, a File directory path is copied and pasted as below:
arch /arm /kernel /stacktrace.c
It just removes the whitespace between directories and makes the
copied string as below:
arch/arm/kernel/stacktrace.c
The output looks same in html format, but the copied directory path
can be pasted as it looks.

This reverts commit r236423 and its followup r236533, as indiscriminate
quoting makes for too much quoting (and clang doesn't like both '"-c"'
and -D"FOO=bar").

This fixes errors that occur if a path to the default compiler has spaces or if an argument with spaces is given to compiler (e.g. via -I). (http://reviews.llvm.org/D9357)
