Summary:

Create a new Frontend LangOpt to specify the renderscript language. It
is enabled by the "-x renderscript" option from the driver.

Add a "kernel" function attribute only for RenderScript (an "ignored
attribute" warning is generated otherwise).

Make the NativeHalfType and NativeHalfArgsAndReturns LangOpts be implied
by the RenderScript LangOpt.

[Driver] Fix driver support for color diagnostics

Diagnostics that happen during driver time do not have color output support
unless -fcolor-diagonostic is explicitly passed into the driver. This is not a
problem for cc1 since dianostic arguments are properly handled and color is
enabled by default if the terminal supports it.

Make the driver behave like CC1. There are tests that already check for these
flags, but for the color itself there's no sensible way to test it.

[Driver] Add support for -finline-functions and /Ob2 flags

-finline-functions and /Ob2 are currently ignored by Clang. The only way to
enable inlining is to use the global O flags, which also enable other options,
or to emit LLVM bitcode using Clang, then running opt by hand with the inline
pass.

This patch allows to simply use the -finline-functions flag (same as GCC) or
/Ob2 in clang-cl mode to enable inlining without other optimizations.

This is the first patch of a serie to improve support for the /Ob flags.

[ubsan] Add -fsanitize-undefined-strip-path-components=N

Summary:
This option allows the user to control how much of the file name is
emitted by UBSan. Tuning this option allows one to save space in the
resulting binary, which is helpful for restricted execution
environments.

With a positive N, UBSan skips the first N path components.
With a negative N, UBSan only keeps the last N path components.

option is used, clang will embed both the input bitcode and cc1
commandline into the bitcode in special sections before compiling to
the object file. Using -fembed-bitcode-marker will only introduce a
marker in both sections.

Frontend: support -I=path for sysroot expansion

From the GCC manpage:

-I dir
... If dir begins with =, then the = will be replaced by the sysroot prefix;
see --sysroot and -isysroot.

Add support to expand the `=` as a prefix of the include path with the sysroot
if specified. `-isysroot` takes precedence over `--sysroot` as the normal
argument behaviour occurs. The ordering of the `-isysroot` is relevant to the
path substituted. If no `--sysroot=` or `-isysroot` option is present, the = is
not expanded.
