YAMLIO printed a string as is without quotes unless it contains a newline
character. That did not suffice. We also need to quote a string if it starts
with a backquote, quote, double quote or atsign, or it's the empty string.

Some build systems use pipes for stdin/stderr. On nix-ish platforms colored
output can be forced by -fcolor-diagnostics. On Windows this option has
no effect in these cases because LLVM uses the console API (which only
operates on the console buffer) even if a console wrapper capable of
interpreting ANSI escape codes is used.

The -fansi-escape-codes option allows switching from the console API to
ANSI escape codes. It has no effect on other platforms.

In some cases (e.g. when a build system pipes stderr) the Windows console
API cannot be used to color output. For these, provide a way to switch to
ANSI escape codes. This is required for Clang's -fansi-escape-codes option.

[python-bindings] Added code for loading a module from bitcode, getset its datalayout, getset its target, dump it, print it to a file.

llvm-svn: 190458

[python-bindings] Added bindings for LLVMContextRef and a test for creating a new context or getting the global context.

llvm-svn: 190457

[python-bindings] Implemented the PassRegistry class and the calls to initialize/shutdown llvm. Also included an initialize_llvm declaration.

trunk clang is a bit more aggressive about emitting unused-declaration
warnings, so adjust some AST code to match.  Specifically, use
LLVM_ATTRIBUTE_UNUSED for declarations which are never supposed to be
referenced, and turn references to declarations which are supposed to be
referenced into odr-uses.

Make sure we perform the correct "referenced-but-not-used" check for

Process::GetEnv() uses GetEnvironmentVariableW, which is a Windows API
to get an environment variable and is preferable over getenv().

This adds driver support for building DLLs (the /LD and /LDd flags).
It basically does two things: runtime selection and passing -dll and
-implib to the linker.
