llvm-symbolizer: Add a FRAME command.
This command prints a description of the referenced function's stack frame. For each formal parameter and local variable, the tool prints: - function name - variable name - file/line of declaration - FP-relative variable location (if available) - size in bytes - HWASAN tag offset This information will be used by the HWASAN runtime to identify local variables in UAR reports. Differential Revision: https://reviews.llvm.org/D63468 llvm-svn: 364225
