Fix up fallout from r187156.

The previous change caused the driver to translate -Wa,-L to the
-msave-temp-labels option for cc1as, but cc1as did not accept that option.
This patch follows the same approach used for similar options (-relax-all,
-noexecstack) in the previous patch.

Sema: Respect -fdelayed-template-parsing when parsing constexpr functions

Functions declared as constexpr must have their parsing delayed in
-fdelayed-template-parsing mode so as not to upset later template
instantiation.

N.B. My reading of the standard makes it seem like delayed template
parsing is at odds with constexpr.  We may want to make refinements in
other places in clang to make constexpr play nicer with this feature.

This fixes PR17334.

AST: Handle qualified array types in typeid() expressions

The intent of getTypeOperand() was to yield an unqualified type.
However QualType::getUnqualifiedType() does not strip away qualifiers on
arrays.

N.B.  This worked fine when typeid() was applied to an expression
because we would inject as implicit cast to the unqualified array type
in the AST.

We previously handled one-dimensional arrays but didn't consider the

Correctly indent with tabs when whitespace starts from the column not divisible by TabWidth.

Summary:
The width of the first inserted tab character depends on the initial
column, so we need to handle the first tab in a special manner.

Implemented tab usage only for indentation (http://llvm.org/PR17363)

Summary:
Changed UseTab to be a enum with three options: Never, Always,
ForIndentation (true/false are still supported when reading .clang-format).
IndentLevel should currently be propagated correctly for all tokens, except for
block comments. Please take a look at the general idea before I start dealing
with block comments.
