Disassembly currently begins from addresses obtained from the objects
symbol table. For ELF, add the dynamic symbols to the list if no
static symbols are available so that we can more successfully
disassemble stripped binaries.

This test is under 'ArgumentPromotion' but there are no arguments that
get promoted in the test case, so there seems to be no point. Also,
there are no assertions about the output at all, so this seems like
something we should just delete given the low value.

A previous change seems to have remove #includes from header files. This
fixes the build.

renaming things to at least have somewhat spelled out names, and even
have meaningful names where I could guess at what they should be.

Also add FileCheck assertions that we're actually doing what we set out
to do for some of the tests, for example not promoting a type that would
result in infinite promotion.

This feature flag indicates that the processor has support for removing certain instructions from user mode software. But the feature flag by itself doesn't indicate if the support is enabled in the OS. The affected instructions aren't even instructions the compiler would emit. So I don't think think this feature flag should be in the compiler.

It doesn't make any sense to pass in to what is supposed to be parsing

Add support for weak hooks on Windows, as we do on Linux and Darwin.
As we use the macro: `SANITIZER_INTERFACE_WEAK_DEF()` it was not necessary to
modify the header file: `sanitizer_common_interceptors.h`.

After this diff, many tests were fixed for libFuzzer.

[X86] Remove the VMFUNC feature flag. It was only partially implemented and we have no support for codegening vmfunc instructions today.

If that support ever gets added, the full feature flag support should come along with it.

Summary:
This teaches clang how to parse and lower the 'interrupt' and 'naked'
attributes.

This allows interrupt signal handlers to be written.

Summary:
The Mips target is the only user of mnemonicIsValid. This patch
moves this method from AsmMatcherEmitter.cpp to MipsAsmParser.cpp,
getting rid of the method in all other targets where it generated
warnings about an unused function.

This reverts commit r294398, it seems to be failing on the bots.

llvm-svn: 294399

Summary:
After the DFS order change for LVI, i have a few testcases that now
take forever.

The TL;DR - This is mainly due to the overdefined cache, but that
requires predicateinfo to fix[1]

In order to maximize reuse of the LVI cache for now, change the order
we iterate in.

This reduces my testcase from 5 minutes to 4 seconds.

I have verified cases like gmic do not get slower.

I am playing with whether the order should be postorder or idf.

[1] In practice, overdefined anywhere should be overdefined
everywhere, so this cache should be global.  That also fixes this bug.
The problem, however, is that LVI relies on this cache being filled in
per-block because it wants different values in different blocks due to
precisely the naming issue that predicateinfo fixes.  With
predicateinfo, making the cache global works fine on individual
passes, and also resolves this issue.
