Vedant Kumar c418b5cc25 [IRMemoryMap] Use labels in the "malloc" and "free" lldb-test commands
Change the syntax of the malloc and free commands in lldb-test's
ir-memory-map subcommand to:

  <malloc> ::= <label> = malloc <size> <alignment>

  <free> ::= free <label>

This should make it easier to read and extend tests in the future, e.g
to test IRMemoryMap::WriteMemory or double-free behavior.

Vedant Kumar cc5a6163a4 [IRMemoryMap] Test interleaved Mallocs and Frees
This adds a new command to the ir-memory-map tester:

  free <allocation-index>

The argument to free is an index which identifies which live allocation
to free. Index 0 identifies the first live allocation in the address
space, index 1 identifies the second, etc. where the allocations are
sorted in increasing order.

For illustrative purposes, assume malloc returns monotonically
increasing addresses. Here are some examples of how free would work:

Example 1
---------

malloc 16 1
malloc 32 1
free 1      //< Free the 32-byte allocation.
free 0      //< Next, free the 16-byte allocation.

Example 2
---------

malloc 16 1
malloc 32 1
free 0      //< Free the 16-byte allocation.
free 0      //< Next, free the 32-byte allocation.
