minify generates "let" statements in conditions without a block

[rsms]

Repro:

if (something) {
  let x = foo(something)
  // console.log(x)
}

Build with:

esbuild --minify --outfile=test.out.js test.js

Expected output:

if(something){let b=foo(something);}

Actual output:

if(something)let b=foo(something);

Running this in Chrome js console yields this error:

Uncaught SyntaxError: Lexical declaration cannot appear in a single-statement context

Alternatively, the “let” is reduced to nothing (since it's unused) in the expected case:

if(something)foo(something);
