James Dennett 596e475725 This makes SemaCodeComplete.cpp more Doxygen-friendly by changing the 
OBJC_AT_KEYWORD_NAME take a string literal argument where previously
its second argument was an unquoted token; macro invocations such as
OBJC_AT_KEYWORD_NAME(NeedAt,{) confuse Doxygen's parser.

While I'm wary of changing code (rather than just comments) to work
around Doxygen's limitations, in this case the change makes the code
more readable for human beings as well, and the macro derived no
benefit from using the preprocessor's stringification operator, as
it never has need of the unquoted token.

I've also included a couple of trivial drive-by fixes to doc comments.

Akira Hatanaka 5ac78681c1 Bundle jump/branch instructions with the instructions in the delay slot in 
delay slot filler pass of MIPS, per suggestion of Jakob Stoklund Olesen.

This change, along with the fix in r158154, enables machine verification
to be run after delay slot filling.

James Dennett b9199ee5c1 More doxygen/documentation cleanups. 
This reduces the number of warnings generated by Doxygen by about 100
(roughly 10%).  Issues addressed:
(1) Primarily, backslash-escaped "@foo" and "#bah" in Doxygen comments
when they're not supposed to be Doxygen commands or links, and
similarly for "<baz>" when it's not intended as as HTML tag;
(2) Changed some \t commands (which don't exist) to \c ("to refer to a
word of code", as the Doxygen manual says);
(3) \precondition becomes \pre;
(4) When touching comments, deleted a couple of spurious spaces in them;
(5) Changed some \n and \r to \\n and \\r;
(6) Fixed one tiny typo: #pragms -> #pragma.

This patch touches documentation/comments only.

Akira Hatanaka df5205ef3d Implement a DAGCombine in MipsISelLowering.cpp which transforms the following 
pattern:

(add v0, (add v1, abs_lo(tjt))) => (add (add v0, v1), abs_lo(tjt))

"tjt" is a TargetJumpTable node.

Richard Smith 8acadcb84b Add -isystem-prefix and -ino-system-prefix arguments, which can be used to 
override whether headers are system headers by checking for prefixes of the
header name specified in the #include directive.

This allows warnings to be disabled for third-party code which is found in
specific subdirectories of include paths.
