instead of returning the UUID through by-ref argument and a boolean
value indicating success, we can just return it directly. Since the UUID
class already has an invalid state, it can be used to denote the failure
without the additional bool.

Summary:
`clang-cl` can't compile tests containing `char16_t` and `char32_t` types
without the MSVC compatibility option passed. This patch adds the option to the
`clang-cl` call in the `build.py` script by default.

Summary:
For example, if an index symbol has location in a .proto file and an AST symbol
has location in a generated .proto.h file, then we prefer location in .proto
which is more meaningful to users.

Also use `mergeSymbols` to get the preferred location between AST location and index location in go-to-def.

The python documentation says "it’s highly recommended that you use raw strings for all but the simplest expressions." (https://docs.python.org/3/library/re.html)

So do that with the attached patch generated by

    sed -i -e "s/re.search('/re.search(r'/g" $(git grep -l 're.search(')

The warning can be seen in e.g. python3.7:

    $ python3.7 -Wd
    >>> import re; re.search('\s', '')
    <stdin>:1: DeprecationWarning: invalid escape sequence \s

In case of bottlenecks caused by pipeline pressure, we want to be able to
correctly report the set of problematic pipelines. This is a first step towards
adding support for bottleneck hints in llvm-mca (see PR37494). No functional

Summary:
This adds support for auto-detection of path style to SymbolFileBreakpad
(similar to how r351328 did the same for DWARF). We guess each file
entry separately, as we have no idea which file came from which compile
units (and different compile units can have different path styles). The
breakpad generates should have already converted the paths to absolute
ones, so this guess should be reasonable accurate, but as always with
these kinds of things, it is hard to give guarantees about anything.

In an attempt to bring some unity to the path guessing logic, I move the
guessing logic from inside SymbolFileDWARF into the FileSpec class and
have both symbol files use it to implent their desired behavior.

There are certain unsafe or deprecated (since C11) buffer handling
functions which should be avoided in safety critical code. They
could cause buffer overflows. A new checker,
'security.insecureAPI.DeprecatedOrUnsafeBufferHandling' warns for
every occurrence of such functions (unsafe or deprecated printf,
scanf family, and other buffer handling functions, which now have
a secure variant).

This reverts r353677.

llvm-svn: 353686

Allow the use of ninja instead of make. This is useful on some
platforms where we'd like to be able to limit the number of link jobs
without slowing down the other steps of the release.

This patch adds a -use-ninja command line option, which sets the
generator to Ninja both for LLVM and the test-suite. It also deals with
some differences between make and ninja:
* DESTDIR handling - ninja doesn't like this to be listed after the
  target, but both make and ninja can handle it before the command
* Verbose mode - ninja uses -v, make uses VERBOSE=1
* Keep going mode - make has a -k mode, which builds as much as possible
  even when failures are encountered; for ninja we need to set a hard
  limit (we use 100 since most people won't look at 100 failures anyway)

I haven't tested with gmake.

We add a new test to show that redecl chains are not handled properly
