Describe the bug

Some identifiers are not demangled, for example

        jmp     qword ptr [rip + _ZN4core3fmt3num3imp54_$LT$impl$u20$core..fmt..Display$u20$for$u20$usize$GT$3fmt17h7bbbd896a38dcccaE@GOTPCREL]
        mov     edx, OFFSET FLAT:_ZN1a1gEi

Steps to reproduce

Write some code that (for example) is compiled to a rip-relative jump: https://godbolt.org/z/5zWGxhxKq

Expected behavior

The identifiers should be demangled.

I believe these regexes are too restrictive?

compiler-explorer/lib/demangler/base.ts

Line 47 in a47d3c6

readonly jumpDef = /(j\w+|b|bl|blx)\s+([$_a-z][\w$@]*)/i;

Line 55 in a47d3c6

readonly movUnderscoreDef = /mov.*\s(_[\w$.@]*)/i;
