Get back getHostTriple.

For JIT compilation, use the host triple instead of the default
target: this fixes some JIT testcases that used to fail when the
compiler has been configured as a cross compiler.

to include -- in sample command lines.  Now LLDB
prints

  expression [-f <format>] -- <expr>

instead of

  expression [-f <format>] <expr>

and also adds a new example line:

  expression <expr>

to show that in the absense of arguments the --
can be ommitted.

eFormatCString is specified, I have made
DataExtractor::Dump properly escape the string.
This prevents LLDB from printing characters
that confuse terminals.

different modules. This implementation is a first approximation of
what we want, using only the function type to determine
equivalence. Later, we'll want to deal with some of the more subtle
issues, including:

  - C allows a prototyped declaration and a non-prototyped declaration
    to be merged, which we should support
  - We may want to ignore the return type when merging, then
    complain if the return types differ. Or, we may want to leave it
    as it us, so that we only complain if overload resolution
    eventually fails.
  - C++ non-static member functions need to consider cv-qualifiers
    and ref-qualifiers.
  - Function templates need to consider the template parameters and
    return type.
  - Function template specializations will have special rules.
  - We can now (accidentally!) end up overloading in C, even without
    the "overloadable" attribute, and will need to detect this at some
    point.
  
The actual detection of "is this an overload?" is implemented by
Sema::IsOverload(), which will need to be moved into the AST library
for re-use here. That will be a future refactor.

modules, so long as the typedefs refer to the same underlying
type. This ensures that the typedefs end up in the same redeclaration
chain.

To test this, fix name lookup for C/Objective-C to properly deal with
multiple declarations with the same name in the same scope.

Add an explicit LambdaExprContext to Declarator, to parallel BlockLiteralContext.  Use it to ensure semantic analysis of types isn't confused by the lack of a type specifier.

(x > y) ? x : y
=>
(x >= y) ? x : y

So for something like
(x - y) > 0 : (x - y) ? 0
It will be
(x - y) >= 0 : (x - y) ? 0

This makes is possible to test sign-bit and eliminate a comparison against
zero. e.g.
subl   %esi, %edi
testl  %edi, %edi
movl   $0, %eax
cmovgl %edi, %eax
=>
xorl   %eax, %eax
subl   %esi, $edi
cmovsl %eax, %edi

Get rid of an unnecessary check; the AST for init-lists is the same independent of whether we're in C++11 mode.

Before we'd get:

$ clang t.c 
fatal error: error in backend: Invalid operand for inline asm constraint 'i'!

Now we get:

$ clang t.c
t.c:16:5: error: invalid operand for inline asm constraint 'i'!
    "movq         (%4), %%mm0\n"
    ^

Which at least gets us the inline asm that is the problem.

Minor tweak to name lookup for C/Objective-C: after the first name, still consider whether this is a redeclaration lookup when determining whether to look for the visible declaration

llvm-svn: 147499

the AST reader doesn't actually perform a merge, because name lookup
knows how to merge identical typedefs together.

As part of this, teach C/Objective-C name lookup to return multiple
results in all cases, rather than first digging through the attributes
to see if the value is overloadable. This way, we'll catch ambiguous
lookups in C/Objective-C.
