Fix several tuple bugs that were exposed by clang's implementation of CWG 1402.  This fixes http://llvm.org/bugs/show_bug.cgi?id=17798.

We can change this back when NEON support is complete and ready to become
enabled by default.

llvm-svn: 194152

Fix an off-by-one error in basic_string::__grow_by, where it would incorrectly throw length_error (instead of bad_alloc) when attempting to resize the string to 'max_size()'. Add tests for resizing to max_size +/-1

I don't have a standalone testcase for this, but it should allow r193676
to be reapplied.

Implement gpword directive for mips, test case added. Stype changes using clang-format are also included.

Presence of using namespace llvm depended on several #ifdef's, and
this broke the build on mswin32.

Also, properly name the functions.

/section command line option is to set/reset attributes of the Characteristics
field in the section header. You can set non-default values with this option.
You can make .data section executable with this, for example.

This patch implements the parser of the command line option. The code to use
the parsed values will be committed in a separate patch.

I'm not sure if it is really an alias for /nodefaultlib, but I can say that
they are at least similar. Making it an alias would be better than ignoring it.

/defaultlib options can be specified implicitly via the .drectve section, and
it's pretty common that multiple object files add the same library, such as
user32.lib, to the input. We shouldn't add the same library multiple times.

We wrapped the linker internal file with a virtual archive file, so that the
linker internal file was linked only when it's actually used. This was to avoid
__ImageBase being included to the resulting executable. __ImageBase used to
occupy four bytes when emitted to executable.

And then it turned out that the implementation of __ImageBase was wrong -- it
shouldn't have been a regular atom but an absolute atom. Absolute atoms point
to some memory location, but they don't occupy disk space themselves. So it
wouldn't increase executable size (except the symbol table.) That means that
it's OK to link the linker internal file unconditionally.

So this patch does that, removing the wrapper archive file. Doing this
simplifies the code.

Patch by Michele Scandale!

Rewrite of the functions used to compute the backedge taken count of a
loop on LT and GT comparisons.

I decided to split the handling of LT and GT cases becasue the trick
"a > b == -a < -b" in some cases prevents the trip count computation
due to the multiplication by -1 on the two operands of the
comparison. This issue comes from the conservative computation of
value range of SCEVs: taking the negative SCEV of an expression that
have a small positive range (e.g. [0,31]), we would have a SCEV with a
fullset as value range.

Indeed, in the new rewritten function I tried to better handle the
maximum backedge taken count computation when MAX/MIN expression are
used to handle the cases where no entry guard is found.

Some test have been modified in order to check the new value correctly
(I manually check them and reasoning on possible overflow the new
values seem correct).

I finally added a new test case related to the multiplication by -1
issue on GT comparisons.

This patch adds the same behavior to clang.
