Reid Kleckner 67d440b949 Print quoted backslashes in LLVM IR as \\ instead of \5C
This improves readability of Windows path string literals in LLVM IR.
The LLVM assembler has supported \\ in IR strings for a long time, but
the lexer doesn't tolerate escaped quotes, so they have to be printed as
\22 for now.

Andrew Ng ac305e18a4 [ThinLTO] Escape module paths when printing
We have located a bug in AssemblyWriter::printModuleSummaryIndex(). This
function outputs path strings incorrectly. Backslashes in the strings
are not correctly escaped.

Consequently, if a path name contains a backslash followed by two
hexadecimal characters, the sequence is incorrectly interpreted when the
output is read by another component. This mangles the path and results
in error.

This patch fixes this issue by calling printEscapedString() to output
the module paths.

Patch by Chris Jackson.
