Per latest drafting, switch to implementing init-captures as if by declaring
and capturing a variable declaration, and complete the implementation of them.

Switch from putting init capture VarDecls in the surrounding DeclContext to
putting them in the call operator's DeclContext. This better matches the
language wording and avoids some cases where code gets confused by them for
namespace-scope lambdas and the like.

Separate construction of bi-arch path suffix from construction of
multi-library path suffix.

The code calculates MIPS toolchain specific multi-lib path suffixes like
mips16/soft-float/el is moved to the separate function
findMultiLibSuffix(). This function called during GCC installation
detection and result is stored for the future using.

The patch reviewed by Rafael Espindola.

Refactor comment merging.

- We scan for whitespace between comments anyways, remember any newlines seen
  along the way.
- Use this newline number to decide whether two comments are adjacent.
- Since the newline check is now free remove the caching and unused code.
- Remove unnecessary boolean state from the comment list.
- No behavioral change.
