to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

This commit merges the #ifdef and #ifndef checks into one #if, as
suggested by Duncan P. N. Exon Smith.

This commit moves the APSInt initialization code that's used by
the LLLexer class into a new APSInt constructor that constructs
APSInts from strings.
This change is useful for MIR Serialization, as it would allow
the MILexer class to use the same APSInt initialization as
LLexer when parsing immediate machine operands.

Add some API to `APSInt` to make it easier to compare with `int64_t`.
- `APSInt::compareValues(APSInt, APSInt)` returns 1, -1 or 0 for
greater, lesser, or equal, doing the right thing for mismatched
"has-sign" and bitwidths. This is just like `isSameValue()` (and is
now the implementation of it).
- `APSInt::get(int64_t)` gets a signed `APSInt`.
- `operator<(int64_t)`, etc., are implemented trivially via `get()`
and `compareValues()`.
- Also added `APSInt::getUnsigned(uint64_t)` to make it easier to test
`compareValues()`.

The interaction between defaulted operators and move elision isn't
totally obvious, add a unit test so it doesn't break unintentionally.
