These are the compressed equivalents of the relocations R_RISCV_BRANCH
and R_RISCV_JAL with slightly more complex immediate handling.

There were basically four different orderings: one defined by the
relocations, one by the enum definition of EdgeKind_riscv, one for
mapping the enum values to their names, and one when mapping the
relocations to edge kinds and finally processing them. Chose the
ordering defined by the relocations in the riscv-elf-psabi-doc as
the canonical one.

It is confusing to see "Unrecognized edge kind" in debugging output
for supported relocations; this was probably an oversight in commit
89f546f6ba which added the support.

This patch supports the R_RISCV_JAL relocation.
Moreover, it will fix the extractBits function's behavior as it extracts Size + 1 bits.
In the test ELF_jal.s:
Before:
```
Hi: 4294836480
extractBits(Hi, 12, 8): 480
```
After:
```
Hi: 4294836480
extractBits(Hi, 12, 8): 224
```

In RISCV, temporary symbols will be used to generate dwarf, eh_frame sections..., and will be placed in object code's symbol table. However, LLVM does not use names on these temporary symbols. This patch add anonymous symbols in LinkGraph for these temporary symbols.
