category.  Use this in a few places to eliminate unnecessary TST cases and
do some future-proofing.  Provide terrible manglings for typeof.  Mangle
decltype with some hope of accuracy.

Our manglings for some of the cases covered in the testcase are different
from gcc's, which I've raised as an issue with the ABI list.

splitting, we only get one of them per iteration.  This makes a small but
measurable compile time improvement with -enable-full-load-pre.

which has the label map, switch statement stack, etc. Previously, we
had a single set of maps in Sema (for the function) along with a stack
of block scopes. However, this lead to funky behavior with nested
functions, e.g., in the member functions of local classes.

The explicit-stack approach is far cleaner, and we retain a 1-element
cache so that we're not malloc/free'ing every time we enter a
function. Fixes PR6382.

Also, tweaked the unused-variable warning suppression logic to look at
errors within a given Scope rather than within a given function. The
prior code wasn't looking at the right number-of-errors count when
dealing with blocks, since the block's count would be deallocated
before we got to ActOnPopScope. This approach works with nested
blocks/functions, and gives tighter error recovery.

ordered correctly.  Previously it would get in trouble when
two patterns were too similar and give them nondet ordering.
We force this by using the record ID order as a fallback.

The testsuite diff is due to alpha patterns being ordered
slightly differently, the change is a semantic noop afaict:

Remove the optimize for code size limitation on r67917. Optimize 64-bit imul by constants into leas + shl regardless if optimizing for code size. The size saving from using imulq isn't worth it. Also, the lea and shl instructions may expose further optimization.

Only perform jump checking if the containing function has no errors,
and add the infrastructure needed to do this.

On the testcase in the PR, we produce:
