Still the formatting can be improved, but at least we don't assert any
more. This happened when trying to format lib/Sema/SemaType.cpp.

Added a new "env" regular expression alias. If "env" is typed on its own "settings show target.env-vars" will be run. Otherwise it can be used to set and environment variable: "env FOO=BAR".

This is complicated by backward labels (e.g., 0b can be both a backward label
and a binary zero). The current implementation assumes [0-9]b is always a
label and thus it's possible for 0b and 1b to not be interpreted correctly for
ms-style inline assembly. However, this is relatively simple to fix in the
inline assembly (i.e., drop the [bB]).
This patch also limits backward labels to [0-9]b, so that only 0b and 1b are
ambiguous.

MSVC accepts this:
class A {
A::A();
};
Clang accepts regular member functions with extra qualification as an MS
extension, but not constructors. This changes the parser to defer rejecting
qualified constructors so that the same Sema logic can apply to constructors as
regular member functions. This also improves the error message when MS
extensions are disabled (in my opinion). Before it was:
/Users/jason/Desktop/test.cpp:2:8: error: expected member name or ';' after declaration specifiers
A::A();
~~~~ ^
1 error generated.
After:
/Users/jason/Desktop/test.cpp:2:6: error: extra qualification on member 'A'
A::A();
~~~^
1 error generated.

This redoes how '*' and '&' are classified as pointer / reference markers when
followed by ')', '>', or ','.
Previously, determineStarAmpUsage() marked a single '*' and '&' followed by
')', '>', or ',' as pointer or reference marker. Now, all '*'s and '&'s
preceding ')', '>', or ',' are marked as pointer / reference markers. Fixes
PR14884.
Since only the last '*' in 'int ***' was marked as pointer before (the rest
were unary operators, which don't reach spaceRequiredBetween()),
spaceRequiredBetween() now had to be thought about handing multiple '*'s in
sequence.
Before:
return sizeof(int * *);
Type **A = static_cast<Type * *>(P);
Now:
return sizeof(int**);
Type **A = static_cast<Type **>(P);
While here, also make all methods of AnnotatingParser except parseLine()
private.

DAGCombiner::ReduceLoadWidth was converting (trunc i32 (shl i64 v, 32))
into (shl i32 v, 32) into undef. To prevent this, check the shift count
against the final result size.

Vectors were being manually scalarized by the backend. Instead,
let the target-independent code do all of the work. The manual
scalarization was from a time before good target-independent support
for scalarization in LLVM. However, this forces us to specially-handle
vector loads and stores, which we can turn into PTX instructions that
produce/consume multiple operands.

'R600/SI: Use proper instructions for array/shadow samplers.' removed two
cases from TEX_SHADOW. Vincent Lejeune reported on IRC that this broke some
shadow array piglit tests with the r600g driver. Reinstating the removed
cases should fix this, and still works with radeonsi as well.
I will follow up with some lit tests which would have caught the regression.
NOTE: This is a candidate for the Mesa stable branch.
