Reintroduce the InlineHint function attribute.
...
This time it's for real! I am going to hook this up in the frontends as well.
The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.
We need some experiments to determine if that is the right thing to do.

add the ability for TargetData to return information about legal integer

datatypes on a given CPU. This is intended to allow instcombine and other

legal integer sizes to TargetData" on Feb 1, 2009 on llvmdev, and PR3451.

Make blockaddress(@func, null) be valid, and make 'deleting a basic

block with a blockaddress still referring to it' replace the invalid
blockaddress with a new blockaddress(@func, null) instead of a
inttoptr(1).
This changes the bitcode encoding format, and still needs codegen
support (this should produce a non-zero value, referring to the entry
block of the function would also be quite reasonable).
