6ae7f2b5d8 [arm64] Avoid signed arithmetic in AddWithCarry. 
This avoids implementation-defined signed overflow in the simulator's
AddWithCarry implementation. The implementation of AddWithCarry now uses
unsigned arithmetic exclusively.

Testing coverage is also significantly improved.

09b44428e4 [runtime] First step to sanitize regexp literal creation. 
This is the initial step towards refactoring the regexp literation
creation code to make it less obscure and more similar to the mechanism
we use to create array and object literals.  There's now a new runtime
entry %CreateRegExpLiteral with the same interface as the entries for
array and object literals, except that we still pass the flags as
string.

Instead of embedding the hand written native to clone JSRegExp instances
we now have a FastCloneRegExpStub, which behaves similar to the other
FastCloneShallowArrayStub and FastCloneShallowObjectStub that we already
had.

29f73ad104 [arm64] Fix some signed/unsigned type inconsistencies. 
This fixes several warnings when cross-building using GCC (since r31087,
5cf1c0b).

In particular, CPURegister::code() now returns 'int', matching the other
platforms (and the coding style guide). The rest of the patch consists
of similar changes to make this work.

a904b569a2 Security: disable nontemporals. 
The operations were available on ARM64 and x86-32 but were unused.

It has been conjectured that nontemporals can be used for rowhammer-like bitflips more easily than regular load/store operations. It is therefore desirable to avoid generating these instructions in the future.

7d478d9621 Revert of Remove obsolete V8_INFINITY macro. (patchset #3 id:40001 of https://codereview.chromium.org/798413003/) 
Reason for revert:
Speculative revert. This seems to block the current roll: https://codereview.chromium.org/819653003/

I retried several times, also with a new roll. The error is internal - but that doesn't make much of a difference.

  - Since Printf now records the type and size of each argument, it is
    possible to mix argument types.
  - It is now possible to print the stack pointer. There is only one
    remaining restriction: The `csp` register cannot be printed unless
    it is the current stack pointer. This is because it is modified by
    BumpSystemStackPointer when the caller-saved registers are
