No version of clang installed by XCode, ToT or otherwise recognizes the flag
'-no-intel-extensions' and more recent versions error out on it.

Prospectively conditionalize the flag behind "icc" to fix the mainline build
with clang.

check-tools.pl was hard-wired to expect the Apple compiler version string which
doesn't make much sense, especially for a LLVM project.

The correctness and value of these compiler version checks still isn't clear
following this build fix but they are retained for now.

gcc/g++ don't exist on modern OS X development environments so the failed
checks for gcc were causing the build to break even with 'make compiler=clang'.

(The rationale for the check refers to a file 'touch-test.c' which no longer
exists in the codebase.)

Before this patch we would only use the fist occurance of a matcher
function in the documentation, for example leaving out
hasType(Matcher<QualType>).

1. Move internal functions into ASTMatchersInternal.
2. Adapt dump_ast_matchers.py to the new VariadicOperatorMatcherFunc

3. Update the actual docs with the updated tool / code.

The isPure() CXXMethodDecl matcher matches pure method declaration like "A::x"
in this example:

class A {
  virtual void x() = 0;
}

AdjustStackSizeLinux() is used in Lsan, Tsan and Msan non-Linux-specific code so it seems it should have more generic name and moved to a common scope.
Renamed to AdjustStackSize.
Patch by Viktor Kutuzov.

In 'obsequi' we have a scop in which the current dead code elimination works,
but the generated code is way too complex. To avoid this trouble (and to not
disable the DCE entirely) we add an additional approximative step before
the actual dead code elimination. This should fix one of the two current
nightly-test issues.

Polly could be improved to handle 'obsequi' by teaching it to introduce only a
single parameter for (%1 and zext %1) which halves the number of parameters and
allows polly to derive a simpler representation for the set of live iterations.
However, this needs some time to investigate.

I will commit a test case as soon as we have a reduced one.

Fix an unintentional stdin read in the darwin-asan-nofortify.c test and replace

Most 64-bit targets define int64_t as long int, and AArch64 should
make same definition to follow LP64 model. In GNU tool chain, int64_t
is defined as long int for 64-bit target. So to get consistent with GNU,
it's better Changing int64_t from 'long long int' to 'long int',
otherwise clang will get different name mangling suffix compared with g++.

The .error directive is similar to .err in that it will halt assembly if it is
evaluated for assembly.  However, it permits a user supplied message to be
rendered.

The .ifeqs directive assembles the following code if the quoted string
parameters are equal.  The strings must be quoted using double quotes.

Sven suggested to use this simpler code generation strategy as the convex_hull
computation is apparently rather inefficient. We do not have a test case that
shows a difference, but, in case we find a test case where this makes a
difference, we can reconsider our decission.

- Only include offsets with local (in function scope) symbols, where we don't encode scoping
- Only include the filename with non-system symbols. Presumably the system headers will not provide conflicting definitions.

.align is handled specially on certain targets.  .align without any parameters
on ARM indicates a default alignment (4).  Handle the special case in the target
parser, but fall back to the generic parser for the normal version.

If the strings are not quoted, the first string stops at the first comma, and
the second string stops at the end of the line.  Strings which contain
whitespace should be quoted.  Unquoted space is to be discarded.
