The splitting pass does not need BFI unless the Module actually has a profile
summary. Do not calcualte BFI unless the summary is present.
For the sqlite3 amalgamation, this reduces time spent in the splitting pass
from 0.4% of the total to under 0.1%.

The splitting pass does not need (post)domtrees until after it's found a
cold block. Defer domtree calculation until a cold block is found.
For the sqlite3 amalgamation, this reduces time spent in the splitting
pass from 0.8% of the total to 0.4%.

Some member functions of StringRef/SmallVector/StringSwitch
are marked with the `always_inline` attribute. The result
is that the body of these functions is not emitted, hence the
debugger can't evaluate them (a typical example is
StringRef::size()), even if the code is built with `-O0`.
The main driver behind this was that of getting faster turnaround
when running `check-llvm`. A previous commit clarifies how to
get good performance when running the testsuite, so we can
get rid of the attribute here.
An alternative approach considered was that of using attribute `used`,
but in the end we preferred to not slap yet another attribute on
these functions.

Also add debug prints in the default case of the switches in these routines.
Most if not all of the type legalization handlers already do this so this makes promoting floats consistent

It might be a bit nicer to use the fancy .legalIf and co. predicates,
but this was requiring more boilerplate and disables the coverage
assertions.

If the underlying filesystem does not support mmap system call,
FileOutputBuffer may fail when it attempts to mmap an output temporary
file. This patch handles such situation.
Unfortunately, it looks like it is very hard to test this functionality
without a filesystem that doesn't support mmap using llvm-lit. I tested
this locally by passing an invalid parameter to mmap so that it fails and
falls back to the in-memory buffer. Maybe that's all what we can do.
I believe it is reasonable to submit this without a test.

For AMDGPU the shift amount is never 64-bit, and
this needs to use a 32-bit shift.
X86 uses i8, but seemed to be hacking around this before.

The old diagnostic form of the trace produced by -v and -vv looks
like:
```
check1:1:8: remark: CHECK: expected string found in input
CHECK: abc
^
<stdin>:1:3: note: found here
; abc def
^~~
```
When dumping annotated input is requested (via -dump-input), I find
that this old trace is not useful and is sometimes harmful:
1. The old trace is mostly redundant because the same basic
information also appears in the input dump's annotations.
2. The old trace buries any error diagnostic between it and the input
dump, but I find it useful to see any error diagnostic up front.
3. FILECHECK_OPTS=-dump-input=fail requests annotated input dumps only
for failed FileCheck calls. However, I have to also add -v or -vv
to get a full set of annotations, and that can produce massive
output from all FileCheck calls in all tests. That's a real
problem when I run this in the IDE I use, which grinds to a halt as
it tries to capture all that output.
When -dump-input=fail|always, this patch suppresses the old trace from
-v or -vv. Error diagnostics still print as usual. If you want the
old trace, perhaps to see variable expansions, you can set
-dump-input=none (the default).

Summary:
I did this for two reasons:
- Using the CMake packages simplifies building LLDB Standalone. This is for two
reasons: 1) We were doing a decent amount of work that is already done in the
LLVMConfig.cmake that we want to import, 2) We had to do some manual work to call
llvm-config, parse its output, and populate variables that the build system
uses.
- As far as I understand, using llvm-config makes it difficult if not impossible
to cross-compile LLDB standalone.

I was honestly a bit surprised that we didn't do this before. This
patch is to handle "-" as the stdout so that if you pass `-o -` to
lld, for example, it writes an output to stdout instead of file `-`.
I thought that we might want to handle this at a higher level than
FileOutputBuffer, because if we land this patch, we can no longer
create a file whose name is `-` (there's a workaround though; you can
pass `./-` instead of `-`). However, because raw_fd_ostream already
handles `-` as a special file name, I think it's okay and actually
consistent to handle `-` as a special name in FileOutputBuffer.

Summary:
Shafik found out that importing a CXXConstructorDecl will create a translation unit that
causes Clang's CodeGen to crash. The reason for that is that we don't copy the OperatorDelete
from the CXXConstructorDecl when importing. This patch fixes it and adds a test case for that.
