The llvm-cov ‘report' command displays a summary of the coverage of a binary file.
The summary report currently only includes covered regions and covered functions.
This patch adds the coverage of lines in the summary report.

Summary:
When giving the following command:
% llvm-cov report -instr-profile=default.profraw
llvm-cov will give the following error message:
>llvm-cov report: Not enough positional command line arguments specified!
>Must specify at least 1 positional arguments: See: orbis-llvm-cov report -help
This patch changes the error message from '1 positional arguments'
to '1 positional argument'.

Just because we can constant fold the result of an instruction does not
imply that we can delete the instruction. It may have side effects.
This fixes PR28655.

This change adds a hasFileAtIndex method. getChildDeclContext can first call this method, and if it returns true it knows it can then lookup the resolved path cache for the given file index. If we hit that cache then we don't even have to call getFileNameByIndex.
Running dsymutil against the swift executable built from github gives a 20% performance improvement without any change in the binary.

If `-irce-skip-profitability-checks` is passed in, IRCE will kick in in
all cases where it is legal for it to kick in. This flag is intended to

This makes it easy to swap out the default stylesheet for a custom one.
It also shaves ~6.62 MB out of the report directory for a full coverage
build of llvm+clang.
While we're at it, prune the CSS and add tests for it.

When we failed to parse a function in the mir parser, we should abort
the whole compilation instead of continuing in a weird state. Indeed,
this was creating strange machine function passes failures that were
hard to understand, until we notice that the function actually did not
get parsed correctly!

This variant is (as documented in the TD) for disassembler use only, and should
not be used in patterns - it is longer, and is broken on 64-bit.

when constraint "w" is used on a 32-bit operand.
This enables compiling the following code, which used to error out in
the backend:
void foo1(int a) {
asm volatile ("sqxtn h0, %s0\n" : : "w"(a):);
}
Fixes PR28633.

This does not change anything by default since LLVM_INCLUDE_UTILS is already set
to TRUE by default. In addition, since LLVM_INCLUDE_TESTS => LLVM_INCLUDE_UTILS,
the only way that this can cause changes is in the case where LLVM_INCLUDE_UTILS
is set to TRUE, but LLVM_INCLUDE_TESTS is FALSE. In that case, building gtest is
not a huge cost.
The reason to do this is that without this change, one can not turn off
LLVM_INCLUDE_TESTS in downstream projects that also use gtest for unittests. It
also just in general makes more sense since LLVM_INCLUDE_UTILS gates FileCheck
and other utilities that are along the lines of gtest.
Additionally from talking with chandlerc, this was not done for any specific
reason, so there is no reason not to do it and lots of benefit to doing it.

It's possible to use trunc + icmp sgt/slt in place of an and + icmp eq/ne, so we need to
recognize that pattern to eliminate selects that are choosing between some value and some
bitmasked version of that value.
Note that there is significant room for improvement (refactoring) and enhancement (more
patterns, possibly in InstCombine rather than here).

This patch moves the update instruction for vectorized integer induction phi
nodes to the end of the latch block. This ensures consistent placement of all
induction updates across all the kinds of int inductions we create (scalar,
splat vector, or vector phi).

std::numeric_limits<int64_t>::max() is not constexpr in VC 2013 headers,
