Sean Callanan 393c4df342 Build system fixes. llvm-mc depends on
libEnhancedDisassembly, so we now build the
static library in all cases (although the shared
library is only built when requested/possible).

Also, fixed a bug where edis wasn't properly
initializing the targets it uses.

Chris Lattner 97a8e43a02 fix PR6814 - Only print [-pedantic] on a diagnostic if -pedantic
actually turned it on.  If a diag is produced by a warning which
is an extension but defaults to on, and has no warning group, don't
print any option info.

Ted Kremenek 4ed2925b91 Add 'clang_getCursorLanguage' to return the "language" of the AST element (e.g., distinguish between C and Objective-C language features). Currently this only returns results for declarations.

Dan Gohman 4a645b88ef Suppress LinearFunctionTestReplace when the computed backedge-taken
expression is a UDiv and it doesn't appear that the UDiv came from
the user's source.

ScalarEvolution has recently figured out how to compute a tripcount
expression for the inner loop in
SingleSource/Benchmarks/Shootout/sieve.c, using a udiv. Emitting a
udiv instruction dramatically slows down the enclosing loop.

Chris Lattner 933f67887f fix PR6660/6168: emit padding as zeros instead of undef. Because
trailing fields may not be represented in initializer lists, they
are being handled as padding and those fields *must* be zero 
initialized.

Douglas Gregor 41f9030fb8 Implement C++ [temp.local]p4, which specifies how we eliminate
name-lookup ambiguities when there are multiple base classes that are
all specializations of the same class template. This is part of a
general cleanup for ambiguities in template-name lookup. Fixes
PR6717.

Sean Callanan 2d03d3a8a7 Second try at integrating the edis tester. This
time I use the LIBS variable, which is not subject
to a %.a -> -l% transformation, to link llvm-mc
against libEnhancedDisassembly.

llvm-mc -edis works the same as llvm-mc
-disassemble, but outputs tokens and operands.

Johnny Chen fc93503c59 Fixed a crasher in arm disassembler within ARMInstPrinter.cpp after calling
ARM_AM::getSoImmVal(V) with a legitimate so_imm value: #245 rotate right by 2.
Introduce ARM_AM::getSOImmValOneOrNoRotate(unsigned Arg) which is called from
ARMInstPrinter.cpp's printSOImm() function, replacing ARM_AM::getSOImmVal(V).

Douglas Gregor 940bca7b93 Be sure to instantiate the parameters of a function, even when the
function's type is (strictly speaking) non-dependent. This ensures
that, e.g., default function arguments get instantiated properly.

And, since I couldn't resist, collapse the two implementations of
function-parameter instantiation into calls to a single, new function
(Sema::SubstParmVarDecl), since the two had nearly identical code (and
each had bugs the other didn't!). More importantly, factored out the
semantic analysis of a parameter declaration into
Sema::CheckParameter, which is called both by
Sema::ActOnParamDeclarator (when parameters are parsed) and when a
parameter is instantiated. Previously, we were missing some
Objective-C and address-space checks on instantiated function
parameters.

Fixes PR6733.

Dan Gohman f76210ead8 Rewrite the overflow checking in the get{Signed,Unsigned}Range code for
