Kostya Serebryany ad24c58e16 [sanitizer] increase the maximum size class of the fast allocator. This should save quite a bit of memory in tsan/msan (and later in asan). This also puts more stress on the large allocator. Add a couple of checks

Rafael Espindola 54606d57a2 Add 171048 back but invalidate the cache of all redeclarations when setting
the body of a functions. The problem was that hasBody looks at the entire chain
and causes problems to -fvisibility-inlines-hidden if the cache was not
invalidated.

Original message:

Cache visibility of decls.

This unifies the linkage and visibility caching. I first implemented this when
working on pr13844, but the previous fixes removed the performance advantage of
this one.
This is still a step in the right direction for making linkage and visibility
cheap to use.

Kostya Serebryany 181f504d82 [asan] properly define ASAN_LOW_MEMORY. Due to a mistake it has been always true causing redzone and quarantine sizes to be smaller than it was some time before (and out of sync with the documentation). Also make one test less greedy

Bob Wilson fe73ac34c5 Rename LLVMContext diagnostic handler types and functions.
These are now generally used for all diagnostics from the backend, not just
for inline assembly, so this drops the "InlineAsm" from the names.  No
functional change.  (I've left aliases for the old names but only for long
enough to let me switch over clang to use the new ones.)

NAKAMURA Takumi 04a664e92e [CMake] AddLLVM.cmake: Tweak the corner case that "check-all" doesn't have any tests.
"check-all" can be executed with 0 status, "check-all does nothing, no tools built."

LLVM_EXTERNAL_CLANG_BUILD=OFF LLVM_BUILD_TOOLS=OFF can reproduce this.

Benjamin Kramer 9d46110ff1 Use a std::string rather than a dynamically allocated char* buffer.
This affords us to use std::string's allocation routines and use the destructor
for the memory management. Switching to that also means that we can use
operator==(const std::string&, const char *) to perform the string comparison
rather than resorting to libc functionality (i.e. strcmp).

Bob Wilson 4ed23578da Add LLVMContext::emitWarning methods and use them. <rdar://problem/12867368>
When the backend is used from clang, it should produce proper diagnostics
instead of just printing messages to errs(). Other clients may also want to
register their own error handlers with the LLVMContext, and the same handler
should work for warnings in the same way as the existing emitError methods.

Daniel Jasper 8fbd96855c Let clang-format format itself.
Apply all formatting changes that clang-format would apply to its own source
code. All choices seem to improve readability (or at least not make it worse).
No functional changes.

Daniel Jasper 6d822720f0 Penalize tokens with a lower parenthesis level than the start of the line.
This prevents formattings like this (assuming "parameter" doesn't fit the line):
  bool f = someFunction() && someFunctionWithParam(
      parameter) && someOtherFunction();

Here, "parameter" - the start of line 2 - has a parenthesis level of 2, but
there are subsequent tokens ("&&" and "someOtherFunction") with a lower level.
This is bad for readability as "parameter" hides "someOtherFunction". With this
patch, this changes to:
  bool f = someFunction() &&
           someFunctionWithParam(parameter) &&
           someOtherFunction();

Daniel Jasper 537a29638d Fix formatting over overloaded operators.
This fixes llvm.org/pr14686.

We used to add too many spaces for different versions of overloaded operator
function declarations/definitions. This patch changes, e.g.

  operator *() {}
  operator >() {}
  operator () () {}

to

  operator*() {}
  operator>() {}
  operator()() {}

Nadav Rotem dc0ad92b64 Some x86 instructions can load/store one of the operands to memory. On SSE, this memory needs to be aligned.
When these instructions are encoded in VEX (on AVX) there is no such requirement. This changes the folding
tables and removes the alignment restrictions from VEX-encoded instructions.
