Richard Smith 7d0f7b5e8f Rename {Tuple,Struct}Value -> {Tuple,Struct}Literal. (#3213) 
This better reflects the purpose of these semantics nodes, and prepares
for adding TupleValue and TupleInit nodes to represent forming values
and initializers from literals.

Richard Smith 71e9fb7511 Disable raw IR printing in tests by default. (#3204) 
Add a couple more tests to check/testdata/basic/ to explicitly test the
raw dump.

Jon Ross-Perkins 87d4c2dfc6 Improve testing and handling of unsigned APInt values (#3202) 2023-09-07 18:53:38 +00:00
Richard Smith 80e307e2ce Fix printing of integer literals with the high bit set. (#3201) 
Integer literals are not signed, so don't print them as signed.

Richard Smith 76576c1387 Fix rejection of arrays with eight or nine elements. (#3199) 
In general, LLVM's parsing of decimal integers to `APInt`s forms an
`APInt` that is 4n bits wide, where n is the length of the integer, and
the `isNegative` check only checks the high bit.

In this case, we form an `APInt` that is four bits wide, with the high
bit set, which we reject because we think it's "negative". These two
array lengths are the only ones where this happens -- if the decimal
integer value is two characters long, we form an `APInt` that is eight
bits wide but holds a value < 100, so the high bit is never set, and the
same applies for longer integers too.

An `IntegerLiteral` is never negative, so we don't need the `isNegative`
check, and in fact it only detects the n=8 and n=9 cases.

Jon Ross-Perkins 1c748c0f14 Split semantics into check and sem_ir directories (#3176) 
Continuing along with #3070. Note this is just a file rename, with BUILD
edits; every file previously in semantics/ should show as moved (except
maybe BUILDs, which split).
