This adds some more escaping to try to make it work.

-cc1gen-reproducer driver option
The recommit fixes:
- An MSAN failure (CCPrintOptions wasn't initialized in the Driver)
- Ensures that the strings in the libclang invocation files are escaped
Original message:
This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.
It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version
when generating reproducers.
The new mode emits the information about the temporary files and Libclang-specific information
to stdout using JSON.

This is a follow up to r319702 which records parsing invocations.
These files are not emitted by default, and the client has to specify the
invocation emission path first.

Storing the contents of unsaved files is too expensive.
Instead a hash is stored with a record invocation. When a reproducer is
generated, Clang will compare the stored hashes to the new hashes to determine
if the contents of a file has changed. This way we'll know when a reproducer was
generated for a different source to the one that triggered the original crash.

by client
This patch extends libclang by allowing it to record parsing operations to a
temporary JSON file. The file is deleted after parsing succeeds. When a crash
happens during parsing, the file is preserved and the client will be able to use
it to generate a reproducer for the crash.
These files are not emitted by default, and the client has to specify the
invocation emission path first.

The problem was that text files were open in text mode and Microsoft implementation of fread and write will try to do nasty line-feed conversion which make the line position no longer valid. The fix is to read and write files in binary mode.

on the presence of a 'clang' executable. Simplify
CIndexer::getClangResourcesPath() a bit.
Patch up the CMake makefiles to install headers into two locations in
the build tree, for those silly cases where 'clang' will end up
looking into the wrong build directory for headers.
