Douglas Gregor ffed1cb339 Introduce a limit on the depth of the template instantiation backtrace
we will print with each error that occurs during template
instantiation. When the backtrace is longer than that, we will print
N/2 of the innermost backtrace entries and N/2 of the outermost
backtrace entries, then skip the middle entries with a note such as:

  note: suppressed 2 template instantiation contexts; use
  -ftemplate-backtrace-limit=N to change the number of template
  instantiation entries shown

This should eliminate some excessively long backtraces that aren't
providing any value.

Douglas Gregor c4df407604 Keep track of the actual storage specifier written on a variable or
function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch
by Enea Zaffanella and Paolo Bolzoni.

Chandler Carruth e03aa55bfd Add support for '-fgnu-keywords' and '-fasm' to Clang's driver. They are not
implemented precisely the same as GCC, but the distinction GCC makes isn't
useful to represent. This allows parsing code which uses GCC-specific keywords
('asm', etc.) without parsing in a fully GNU mode.

Benjamin Kramer b11416d061 Add raw_ostream operators to NamedDecl for convenience. Switch over all users of getNameAsString on a stream.
The next step is to print the name directly into the stream, avoiding a temporary std::string copy.

Nick Lewycky 40884c0520 Add a write(raw_ostream&) method to RewriteBuffer. This uses an inefficient
implementation today but is the right place if we want to make it faster some
day.

Dan Gohman 6e8427e066 Remove this hard-coded buffer size. In some basic experiments preprocessing
large files, this doesn't seem significantly better than just letting
raw_ostream pick a buffer size.

This code predates raw-ostream's automatic buffer sizing; in fact, it
was introduced as part of the code which would eventually become
raw_ostream.

Douglas Gregor aef0022925 Fix a bug in caret-line-pruning logic that only happens when we have a
source line wider than the terminal where the associated fix-it line
is longer than the caret line. Previously, we would crash in this
case, which was rather unfortunate. Fixes <rdar://problem/7856226>.

Daniel Dunbar 76fa840d09 Driver/Frontend: Add support for -mllvm, which forwards options to the LLVM option parser.
- Note that this is a behavior change, previously -mllvm at the driver level forwarded to clang -cc1. The driver does a little magic to make sure that '-mllvm -disable-llvm-optzns' works correctly, but other users will need to be updated to use -Xclang.

Douglas Gregor 2d2d90750c Once we've emitted a fatal diagnostic, keep counting errors but with a
separate count of "suppressed" errors. This way, semantic analysis
bits that depend on the error count to determine whether problems
occured (e.g., some template argument deduction failures, jump-scope
checking) will not get confused.

The actual problem here is that a missing #include (which is a fatal
error) could cause the jump-scope checker to run on invalid code,
which it is not prepared to do. Trivial fix for both
<rdar://problem/7775941> and <rdar://problem/7775709>.

Chris Lattner 198cb4df6e Instead of counting totally diagnostics, split the count into a count
of errors and warnings.  This allows us to emit something like this:

2 warnings and 1 error generated.

instead of:

3 diagnostics generated.

This also stops counting 'notes' because they are just follow-on information
about the previous diag, not a diagnostic in themselves.

Chris Lattner 5ec32e7fd8 teach clang to install the inline asm diagnostic handler,
allowing backend errors to be mapped through clang's 
diagnostics subsystem, including the backend location info.

We now get:

$ clang asm.c -c -o t.o -integrated-as
<inline asm>:1:2: error: unrecognized instruction
        abc incl    %eax
        ^
1 diagnostic generated.

With colors, and correct "# diagnostics generated".
