 - On OS X 10.7+ this is apparently recommended practice. This maybe should
   become a configurey thing one day, but I'm not sure it is right to
   automatically turn it on.

 - These functions are both (a) very commonly called and (b) excellent
   candidates for CSE in the callers in which they are commonly used.
 - That isHalfType() is hot makes me sad, but it is trivially when inlined (and
   a huge waste of time when not!!!).
 - The extra IsEnumDeclComplete() function is a hack to break the cycle between
   Type.h and Decl.h, I'm not sure of how to do this more cleanly, but am open
   to ideas.

more aggressive about trapping exceptions than a user would be.  Make it so...

Moves the virtual call out of a hot path during lookup, no other functionality change.

use the first pointer type for it. Rename it to getAddrOfPtr1().

Use uint16_t to store indices into string table since C++ only allows 64K string literals so the index into the big string can never be larger than that.

Fixed STDERR to not be opened as readable. Also cleaned up some of the code that implemented the file actions as some of the code was using the wrong variables, they now use the right ones (in for stdin, out for stdout, err for stderr).

Increase number of allowed registers in register classes to 64k instead of 256. Widen register class ID to 16-bits. Widen register size and alignment to be up to 64k bytes instead of 256 bytes. This partially reverts r152019 to be less restrictive.

grammar requires a string-literal and not a user-defined-string-literal. The
two constructs are still represented by the same TokenKind, in order to prevent
a combinatorial explosion of different kinds of token. A flag on Token tracks
whether a ud-suffix is present, in order to prevent clients from needing to look
at the token's spelling.

It is just a worse version of TinyPtrVector.

llvm-svn: 152097

The latter is just a worse version of the former.

When an instruction only writes sub-registers, it is still necessary to
add an <imp-def> operand for the super-register.  When reloading into a
virtual register, rewriting will add the operand, but when loading
directly into a virtual register, the <imp-def> operand is still
necessary.

Based on a writeup originally by Greg Clayton.

Abuse div and pre tags horribly. Needs a bit more cleanup.
