1) don't delete gtest-all.cc (which is used to gather all gtest source
files in a single file)
2) make including LLVMSupport headers optional (on by default).
Sanitizer tools may want to use their own versions of googletest
compiled with specific flags, instead of the common googletest
library used for all other LLVM/Clang unittests.

understand target implementation of any_extend / extload, just generate
zero_extend in place of any_extend for liveouts when the target knows the
zero_extend will be implicit (e.g. ARM ldrb / ldrh) or folded (e.g. x86 movz).

This is an alternative to the ImmutableMapRef interface where a factory
should still be canonicalizing by default, but in certain cases an
improvement can be made by delaying the canonicalization.

check if loads that happen in between stores alias with the first store in the
chain, only with the second store onwards.

Instead of unconditionally storing origin with every application store,
only do this when the shadow of the stored value is != 0.
This change also delays instrumentation of stores until after the walk over
function's instructions, because adding new basic blocks confuses InstVisitor.
We only keep 1 origin value per 4 bytes of application memory. This change
fixes the bug when a store of a single clean byte wiped the origin for the
whole 4-byte area.
Since stores of uninitialized values are relatively uncommon, this change
improves performance of track-origins mode by 5% median and by up to 47% on
specs.

Some languages, e.g. Ada and Pascal, allow you to specify that the array bounds
are different from the default (1 in these cases). If we have a lower bound
that's non-default, then we emit the lower bound. We also calculate the correct
upper bound in those cases.

RUN: a
RUN: b || true
as "a && (b || true)" in Tcl mode, and as "(a && b) || true" in sh mode.
Everyone seems to (quite reasonably) write tests assuming the Tcl behavior,
so use that in sh mode too.

This is more consistent with other vectors in this code. In addition, I ran some
tests compiling a large program and >96% of fragments have 4 or less fixups, so
SmallVector<4> is a good optimization.

This is much simpler to reason about, more efficient, and
fixes some corner cases involving implicit super-register defs.

The new command line option -unwind-info dumps the Win64 EH unwind
data to the console. This is a nice feature if you need to debug
generated EH data (e.g. from LLVM). Includes a test case.

Change member types of RuntimeFunction and UnwindInfo from uint64_t to
uint32_t:
These members represent addresses. According to MSDN, they are image
relative, that is, they are 32-bit offsets from the starting address
of the image that contains the function table entry.
See MSDN for more information:
RUNTIME_FUNCTION: http://msdn.microsoft.com/en-us/library/ft9x1kdx.aspx
UNWIND_INFO: http://msdn.microsoft.com/en-us/library/ddssxxy8.aspx
Make Win64.h platform-neutral:
The standard types unit8_t, uint16_t and uint32_t are replaced with
their counterparts from Endian.h. Accessor functions are introduced to
replace bit fields.
