Full list of changes:
- all scan-build command-line arguments are now kept in %Options hash.
- most of environment variables scan-build operates with are stored in %EnvVars hash.
- moved processing of command-line arguments to the ProcessArgs subroutine.

It's unlikely to be called frequently and the overhead of using
it in the first place is already factored out.

Summary:
Do not include default sanitizer blacklists into -M/-MM/-MD/-MMD output.
Introduce a frontend option -fdepfile-entry, and only insert them
for the user-defined sanitizer blacklists. In frontend, grab ExtraDeps
from -fdepfile-entry, instead of -fsanitize-blacklist.

This patch depends on r246688 (D12341).
The goal is to make LLVM generate different code for these functions for a target that
has cheap branches (see PR23827 for more details):
int foo();
int normal(int x, int y, int z) {
if (x != 0 && y != 0) return foo();
return 1;
}
int crazy(int x, int y) {
if (__builtin_unpredictable(x != 0 && y != 0)) return foo();
return 1;
}

TagDecls (structs, enums, etc.) may have the same name for linkage
purposes of one another; to disambiguate, we add a number to the mangled
named. However, we didn't do this if the TagDecl has a pseudo-name for
linkage purposes (it was defined alongside a DeclaratorDecl or a
TypeNameDecl).
This fixes PR24651.

the main attribute and cache the results so we don't have to parse
a single attribute more than once.
This reapplies r246596 with a fix for an uninitialized class member,
and a couple of cleanups and formatting changes.

Summary:
`OpaqueValueExpr`s may not have a source expression (as in the case when
they are created due to a default argument error).
This can cause an assertion failure in `TransformOpaqueValueExpr` during
template instantiation.
This patch fixes the assertion failure.

r246546, with a workaround for an MSVC 2013 miscompile and an MSVC 2015
rejects-valid.
Original commit message:
[modules] Rework serialized DeclContext lookup table management. Instead of
walking the loaded ModuleFiles looking for lookup tables for the context, store
them all in one place, and merge them together if we find we have too many
(currently, more than 4). If we do merge, include the merged form in our
serialized lookup table, so that downstream readers never need to look at our
imports' tables.
This gives a huge performance improvement to builds with very large numbers of
modules (in some cases, more than a 2x speedup was observed).

predictable diagnostic experience. The hash-of-DeclID order we were using
before gave different results on Win32 due to a different predefined
declaration of __builtin_va_list.

GCC 4.8+ has a PowerPC-specific intrinsic, __builtin_ppc_get_timebase, to do
what Clang's __builtin_readcyclecounter does. For compatibility with code that
uses GCC's spelling (including glibc), support it as well.
Partially fixes PR23681.

This patch refactors the code to use the GCC installation detector
(modified so that it works in Solaris), and uses
ToolChain::GetFilePath everywhere once it works.

llvm-svn: 246473
A class without a name for linkage purposes gets a name along the lines
of <unnamed-type-foo> where foo is either the name of a declarator which
defined it (like a variable or field) or a
typedef-name (like a typedef or alias-declaration).
We handled the declarator case correctly but it would fall down during
template instantiation if the declarator didn't share the tag's type.
We failed to handle the typedef-name case at all.
Instead, keep track of the association between the two and keep it up to
date in the face of template instantiation.

Also:
- Add a typedef to make working with the result easier.
- Update callers to use the new function.
- Make initFeatureMap out of line.

Proper diagnostic and resolution of mangled names conflicts between C++ methods
and C functions. This patch implements support for functions/methods only;
support for variables is coming separately.

Added codegen for array section in 'depend' clause of 'task' directive. It emits to pointers, one for the begin of array section and another for the end of array section. Size of the section is calculated as (end + 1 - start) * sizeof(basic_element_type).
