627fc538a7 Add new getLibFunc method to TargetLibraryInfo. 
This just provides a way to look up a LibFunc::Func enum value for a
function name.  Alphabetize the enums and function names so we can use a
binary search.

537a3395e5 make all Emit*() functions consult the TargetLibraryInfo information before creating a call to a library function. 
Update all clients to pass the TLI information around.
Previous draft reviewed by Eli.

cc9c07aacc fix pr12559: mark unavailable win32 math libcalls 
also fix SimplifyLibCalls to use TLI rather than compile-time conditionals to enable optimizations on floor, ceil, round, rint, and nearbyint

0e211cfa88 Remove redundant getAnalysis<> calls in GlobalOpt. Add a few Itanium ABI calls 
to TargetLibraryInfo and use one of them in GlobalOpt.

c5fa9f413a Add support for sqrt, sqrtl, and sqrtf in TargetLibraryInfo. Disable 
(fptrunc (sqrt (fpext x))) -> (sqrtf x) transformation if -fno-builtin is 
specified.

d02d82d355 Add support for custom names for library functions in TargetLibraryInfo. Add a custom name for fwrite and fputs on x86-32 OSX. Make SimplifyLibCalls honor the custom 
names for fwrite and fputs.

Fixes <rdar://problem/9815881>.

63dfb2c797 introduce a new TargetLibraryInfo pass, which transformations can use to 
query about available library functions.  For now this just has 
memset_pattern16, which exists on darwin, but it can be extended for a 
bunch of other things in the future.
