Tim Northover 88403d7a84 TableGen: promote "code" type from syntactic sugar. 
It's being immediately converted to a "string", but being able to tell what
type the field was originally can be useful in backends.

Benjamin Kramer 46e38f3678 Avoid copies of std::strings and APInt/APFloats where we only read from it 
As suggested by clang-tidy's performance-unnecessary-copy-initialization.
This can easily hit lifetime issues, so I audited every change and ran the
tests under asan, which came back clean.

Yaron Keren eb2a25467e Annotate dump() methods with LLVM_DUMP_METHOD, addressing Richard Smith r259192 post commit comment. 
clang part in r259232, this is the LLVM part of the patch.

Craig Topper 5e46adb09a [TableGen] Use FoldingSets instead of DenseMaps to unique UnOpInit, BinOpInit and TernOpInit. This remove the memory needed to store the key for the DenseMap. NFC

Matt Arsenault a7bc7db53c TableGen: Support folding casts from bits to int 
This is to fix an incorrect error when trying to initialize
DwarfNumbers with a !cast<int> of a bits initializer.
getValuesAsListOfInts("DwarfNumbers") would not see an IntInit
and instead the cast, so would give up.

It seems likely that this could be generalized to attempt
the convertInitializerTo for any type. I'm not really sure
why the existing code seems to special case the string cast cases
when convertInitializerTo seems like it should generally handle this
sort of thing.

Craig Topper a60ee86f60 [TableGen] Restore the use of the TheInit field in Record to cache the Record's DefInit. I broke this when I fixed memory leaks recently. Remove the DenseMap that mapped Record's to DefInit.

Craig Topper 15864f1518 [TableGen] Merge RecTy::typeIsConvertibleTo and RecTy::baseClassOf. NFC 
typeIsConvertibleTo was just calling baseClassOf(this) on the argument passed to it, but there weren't different signatures for baseClassOf so passing 'this' didn't really do anything interesting. typeIsConvertibleTo could have just been a non-virtual method in RecTy. But since that would be kind of a silly method, I instead re-distributed the logic from baseClassOf into typeIsConvertibleTo.

Craig Topper 2af5e6fbf9 [TableGen] Remove convertValue functions for UnOpInit, BinOpInit, and TernOpInit as they weren't able to be called. 
I don't think converting the inputs to the Ops was the right behavior anyway.

Justin Bogner 1a9ca774b6 TableGen: Avoid undefined behaviour by doing this shift in int64 
Found by ubsan. This was taking a bool and left shifting by 32 - the
result is 64 bit, so we should really do the math in a type it fits
in.

Craig Topper b1846a352e [TableGen] Remove an unnecessary outer 'if' around 3 separate inner ifs. No functional change intended. 
The outer if had 3 separate conditions ORed together and then the inner ifs detected which of the three conditions it was by using only a portion of the specific condition. Just put the whole condition in each inner if and remove the outer if.
