The ARM ACLE describes the values as hex constants rather than numeric
constants; follow suit. Address post-commit review comments from Jon Roelofs.

Extend ARM ACLE support (Section 6.5.1) for AArch32. Define __ARM_FP if
hardware floating point support is available as per the value defined by the
ACLE.

off by default, issue a warning if %s directive is used in
certain CF/NS formatting APIs, to assist user in deprecating
use of such %s in these APIs. rdar://18182443

Because we may change the name of a FileEntry inside getFile, the name
returned by FileEntry::getName() could be destroyed. This was causing a
use-after-free when searching the HeaderFileInfo on-disk hashtable for a
module or pch.

This warning is basically useless because the "previous versions" being referred to is MSVC 2005 and earlier, and we obviously do not care about them. However, this warning isn't particularly chatty (I don't recall ever seeing it previously), and it has the opportunity to point out cases where the cv-qualifiers differ unintentionally (like this case), so I am leaving it enabled for now.

variable that has regiser constraint "r" is not 64-bit.
General register operands are output using 64-bit "x" register names, regardless
of the size of the variable, unless the asm operand is prefixed with the "%w"
modifier. This surprises and confuses many users who aren't familiar with
aarch64 inline assembly rules.
With this commit, a note and fixit hint are printed which tell the users that
they need modifier "%w" in order to output a "w" register instead of an "x"
register.

Name might be empty again after we removed the '%' prefix
and Name[0] would assert.
Found on code like
register int foo asm("%" MACRO);
where MACRO was supposed to be defined in a header file that was not found.

With modules we start accessing headers for the first time while reading
the module map, which often has very different paths from the include
scanning logic.
Using the name by which the file was accessed gets us one step closer to
the right solution, which is using a FileName abstraction that decouples
the name by which a file was accessed from the FileEntry.

And in the process, discover that FileManager::removeStatCache had a
double-delete when removing an element from the middle of the list (at
the beginning or the end of the list, there was no problem) and add a
unit test to exercise the code path (which successfully crashed when run
(with modifications to match the old API) without this patch applied)

class Module. It's almost always going to be the same as
getContainingModule() for top-level modules, so just add a map to cover
the remaining cases. This lets us do less bookkeeping to keep the
ModuleMap fields up to date.

The previous encoding only allowed a single digit for the minor version
number. This changes it to use 2 digits for both the minor version and the
revision number.

intent when we added remark support, but was never implemented in the general
case, because the first -R flags didn't need it. (-Rpass= had special handling
to accomodate its argument.)
-Rno-foo, -Reverything, and -Rno-everything can be used to turn off a remark,
or to turn on or off all remarks. Per discussion on cfe-commits, -Weverything
does not affect remarks, and -Reverything does not affect warnings or errors.
The only "real" -R flag we have right now is -Rmodule-build; that flag is
effectively renamed from -Wmodule-build to -Rmodule-build by this change.
-Wpass and -Wno-pass (and their friends) are also renamed to -Rpass and
-Rno-pass by this change; it's not completely clear whether we intended to have
a -Rpass (with no =pattern), but that is unchanged by this commit, other than
the flag name. The default pattern is effectively one which matches no passes.
In future, we may want to make the default pattern be .*, so that -Reverything
works for -Rpass properly.

Embedded systems seem to have inherited Darwin's choise of "unsigned long" for
size_t (via a bunch of headers), so we should respect that.

Summary:
Adding __int128 support explicitly for x86_64 because currently it's on
only when pointer size >= 64 which is not the case for x32.

char-based types from "char" to "signed char". Adjust stdint.h to use
__INTx_TYPE__ directly without prefixing it with signed and to use
__UINTx_TYPE__ for unsigned ones.
The value of __INTx_TYPE__ now matches GCC.
