31622dd4a9 The Intrinsic::getDeclaration function's Tys parameter only contains the 
types of the iAny types involved in the overloaded intrinsic. Thus, we
can't use the argument number as the index but have to count them separately
in order to index Tys correctly. This patch rectifies this situation.

fe0fe14411 Make tail merging the default, except on powerPC. There was no prior art 
for a target-dependent default with a command-line override; this way
should be generally usable.

1509e17e6c temporarily revert reid's asmwriter patch, it is missing the asmparser piece 
that decodes the escape sequences, thus breaking all cases that use them.

7170d7ab1b Adjust how LLVM names are produced: 
1. Always use % for local and @ for global.
2. Replace NameNeedsQuotes with QuoteNameIfNeeded so that any adjustments
   to the name can be done in one pass.
3. Implement generation of hex escapes so we don't get "wonky" characters
   in the output.

2fc9ebc62a On Linux platforms and at optimization levels -O1 and above, llvm-gcc can 
turn "putchar" calls into _IO_putc calls which is a lower-level interface.
This patch allows these calls to be executed by lli in interpreter mode.
